describe the difference between population,community, organism,and ecosystem

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.

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.

An ecosystem refers to a community of living organisms (plants, animals, and microbes) interacting with each other and the nonliving components (air, water, and soil) in their environment. It can be as small as a pond or as large as a forest or desert.

Examples of nonliving things in an ecosystem include sunlight, water, air, rocks, soil, and minerals.

Factors that could affect the number of organisms in an ecosystem include the availability of food and water, temperature, weather conditions, availability of shelter or habitats, the presence of predators and disease, and human activities such as deforestation or pollution.

Organisms interact in an ecosystem to obtain resources such as food, water, shelter, and mates, and to avoid being eaten by predators or infected by diseases. Some organisms also form mutualistic relationships, where both parties benefit from the interaction.

Different ecosystems can have different organisms and interactions based on the unique features of each ecosystem, such as climate, geography, and available resources.

Understanding feeding relationships in an ecosystem is important because it helps us understand the flow of energy and nutrients through the ecosystem. This knowledge can inform conservation efforts and help us manage and protect ecosystems for the benefit of all living organisms, including humans.

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.

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.
