All organisms must obtain energy from their environment All organisms must obtain energy from their environment. Every organism needs this energy in order to grow and reproduce. How do producers obtain energy? A. They obtain energy by eating plants, bacteria, and algae. B. They extract chemical energy from decaying organic matter. C. They extract energy from the chemicals in soil, air, and water. D. They capture energy from sunlight and manufacture their own food.

Why are decomposers an essential part of a healthy ecosystem?   A. Decomposers are a necessary part of the diet of most consumers. B.Decomposers convert plant material into a form that primary consumers can use. Decomposers make resources available to producers by breaking down waste materials. Decomposers extract energy from sunlight as they break down plant materials, adding returning energy to the system.

Energy transfer A. Increases by 10% as the trophic levels move up the food chain. B. Remains constant regardless of moving up or down on the food chain. C. Varies with the ecosystem it is in. D. Loses about 10% as the trophic levels move up the food chain.

A food web Shows all choices of food that predators can choose. Shows the feeding relationships among organisms in an ecosystem. Is the path of energy transfer from producers to consumers. Shows where all organisms get their nutrients from.

During the 1930s, a large region of the Great Plains experienced a drought that turned grasslands into dust. How did this change most likely affect populations of insects living among the grasslands?   
A. They adapted to eat dust instead of grass. 
B. They decreased because the resources they needed were not available. 
C. They increased because other populations were eliminated from the environment. D.They were not affected because the size of a population cannot change over time.

Some consumers, such as many flying insects, need large amounts of energy to grow and move from one place to another. How do consumers get energy to function?   
A. Consumers obtain all of their energy by eating other organisms.
 B. Consumers obtain some energy from other organisms and some from sunlight. 
C. Consumers obtain most of their energy by absorbing it from their environments. D. Consumers convert light energy from the sun into chemical energy stored in food.
