Answer:
1. An ecosystem is a system of interactions between living and nonliving things in a particular environment.
2. Some examples of nonliving things in an ecosystem include sunlight, soil, rocks, air, water, and temperature.
3. Factors that could affect the number of organisms in an ecosystem include availability of resources, predation, competition, and environmental changes.
4. Organisms interact in an ecosystem in order to find food, to find mates, to escape predators, and to compete for resources.
5. No, you would not expect to find the same kinds of interactions between organisms in very different ecosystems due to differences in biotic and abiotic factors.
6. It is important to understand feeding relationships in an ecosystem because understanding these relationships gives us insight into the stability, dynamics, and functioning of the overall ecosystem. It can also provide an understanding of how the ecosystem may respond to environmental changes.
One side of the heart pumps blood to the ____ and the other pumps blood to the ______.
organs, brain
alveoli, lungs
lungs, rest of the body
brain, rest of body
Answer:
The right ventricle pumps the low-oxygen blood to the lungs to pick up a fresh supply of oxygen. The left atrium receives to high-oxygen blood from the lungs and pumps it to the left ventricle. The left ventricle pumps the high-oxygen blood to the rest of the body.
Answer:
lungs, rest of the body.
Explanation:
Right atrium and Right ventricle pump deoxygenated blood to lungs while Left atrium and Left ventricle pump oxygenated blood to body.
Pointed teeth help tear apart food, and large, flat teeth are used to grind food. Based on this information, what types of teeth are characteristic of animals that eat plants and animals that eat other animals?
Answer:
Flat teeth are characteristic of animals that eat grass, because they grind food in the form of grass in the oral cavity. And predators need sharp teeth in order to tear off flesh, they often do it poorly chewed, and swallowed whole as soon as the flesh was torn off. This is because herbivores can move their jaws to the left and right, while carnivores cannot.
Answer:
Explanation:-
The type of teeth in animals that eat plants are flat teeth used to grind food. The type of teeth in animals that eat other animals are pointed teeth that help tear apart food.
Herbivores are the animals that fall into the category of plant eating animals. They usually feed on plants which require grinding. They ,hence, have large and flat premolars which are highly functional in chewing the plants. These teeth also help in digestion of herbivores. Since, there is no tearing flesh ,the canines are not of much use. On the other hand, carnivores are the animals that fall into the category that eat other animals. They feed on flesh which require tearing so they have sharp canines to rip the flesh.

The 10% rule states that only 10% of the energy stored as biomass at one level is available for the following level. Diatoms are the organisms with the most available energy.
What is the 10% rule?
The 10% rule refers to the energy flow along the trophic chains from autotrophs to heterotrophs and detritivorous organisms.
From the solar energy input, it occurs a unidirectional energy flow through all the organisms in the ecosystem.
Only 1% of the solar energy that reaches the Earth's surface is absorbed by autotroph organisms.
From there, each trophic level transmits 10% of its energy to the following trophic level. The remaining 90% is lost to the environment as heat.
According to these amounts, The 10% rule states that only about 10% of the energy stored as biomass at one trophic level per unit of time ends up as biomass at the next trophic level, in the same unit of time.
In the exposed trophic web, and following the 10% rule, diatoms are the organisms with the most available energy considering their biomass. Only 10% of its energy will be transferred to the second level, 1% to the third level, 0.1% to the fourth level, and 0.01% to the fifth level.

Myth: Tigers and goldfish are not related.

Answer:
Myth: Tigers and goldfish are not related.
Fact: Tigers and goldfish are not closely related according to their genetic and biological classification.
Evidence: Tigers belong to the Panthera genus in the family Felidae, which means they are a type of big cat. Goldfish, on the other hand, belong to the Carassius genus in the family Cyprinidae, which is a type of small freshwater fish. While both are animals, their biology and genetic make-ups are different and they are not closely related to each other.
Myth: An organism's kingdom only describes physical characteristics.
Fact: An organism's kingdom classification is based on their cell type, method of obtaining energy, and other biological characteristics, not solely their physical features.
Evidence: The five kingdoms of life, namely Monera, Protista, Fungi, Plantae, and Animalia, are characterized by their distinct cellular structures, methods of obtaining energy, and other features. For example, animals are multicellular, heterotrophic organisms that rely on consuming other organisms for energy, while plants are autotrophic, photosynthetic organisms that use sunlight and carbon dioxide to produce energy. These biological factors determine an organism's kingdom classification.
Myth: Mammals and plants don't belong in the same domain.
Fact: Mammals and plants belong to different domains of life, but they both belong to the larger group known as eukaryotes, meaning they have cells with a nucleus.
Evidence: The three domains of life are Archaea, Bacteria, and Eukarya. Mammals, along with other animals, fungi, and protists, belong to the Eukarya domain, while plants belong to the Plantae kingdom within the same domain. Despite their differences, both groups share similar cell structures and other characteristics that distinguish them from the other two domains, Archaea and Bacteria.
Myth: Tigers and goldfish are not related.
Fact: Tigers and goldfish are not closely related in terms of their species. Tigers belong to the Felidae family and are classified as mammals, while goldfish belong to the Cyprinidae family and are classified as fish. However, both tigers and goldfish belong to the broader category of animals, as they are both living organisms.
Evidence: The classification system in biology groups organisms based on their similarities and differences. Tigers and goldfish belong to different families within the animal kingdom, indicating that they are not closely related.

Myth: An organism's kingdom only describes physical characteristics.
Fact: An organism's kingdom classification does consider physical characteristics, but it also takes into account other factors such as cell type, mode of nutrition, and reproductive strategies. Physical characteristics alone are not sufficient to determine an organism's kingdom.
Evidence: The five main kingdoms in the classification system are Monera (prokaryotes), Protista (eukaryotes that are not plants, animals, or fungi), Fungi (eukaryotic decomposers), Plantae (eukaryotic photosynthetic organisms), and Animalia (eukaryotic multicellular organisms). These kingdoms are based on a combination of physical characteristics, cellular organization, and other traits.

Myth: Mammals and plants don't belong in the same domain.
Fact: Mammals and plants do not belong in the same domain. Mammals belong to the domain Eukarya, while plants belong to the same domain. Both domains have distinct characteristics and are separate classifications in the biological classification system.
Evidence: The three main domains in the classification system are Bacteria, Archaea, and Eukarya. Mammals, including humans, belong to the domain Eukarya, which also includes other organisms with complex cellular structures. Plants, on the other hand, are also classified under the domain Eukarya. Both mammals and plants have eukaryotic cells, but they have different characteristics and evolutionary histories.

James is investigating the germination of bean seeds. He plants 30 bean seeds each in three identical 30-centimeter-by-30-centimeter square containers and plans to give the same amount of sunlight and water to each container. He will place each container in a different room, with each room at a different temperature. Which of these hypotheses is the most appropriate for this research project? If the size of the container increases, then the number of seeds that germinate will increase. If the temperature of the room decreases, then the number of seeds that germinate will decrease. If the amount of water given to the seeds increases, then the number of seeds that germinate will increase. If the number of seeds planted in the container increases, then the number of seeds that germinate will decrease.
Answer:
The amount of sunlight
Explanation:
The sun is independent but the plants are dependent on the sunlight
