False
Which statement best describes how the matter is transferred between decomposers and plants?
Decomposers are the top of the food chain. Matter and energy from decomposers are released into the ecosystem.
Decomposers break down organisms and return nutrients to the soil. Plants need those nutrients to survive.
Decomposers transfer matter from the air to the soil. The plants consume that matter for energy
Plants are producers. They use energy from the sun to grow.
Walter researches a forest ecosystem for his science fair project. He made a model of a forest food web to explain how matter moves among organisms in the ecosystem. He studied his model and realized he could make an improvement.
How could Walter improve his forest food web model to best explain how matter cycles among organisms and the environment?
He should add the right climate to explain how the plants and animals survive in their environment.
He should add decomposers to explain how they break down dead organisms and restore some materials to the soil.
He should add a rabbit to the food chain to include more forest animals and explain how animals compete for grass.
He should add air to explain how the different organisms in the forest use the gases in the air to survive.
