Describe how the water plants and orchid obtain and release matter into the air.
Hint think of photosynthesis.
Plants need carbon dioxide from the air, and need water to live; they give off gases (oxygen) and water as waste.
These organisms are from a Food Web, how does it effect the environment in its ecosystem? Match the Animal to the effect.
Organisms: Butterfly, Mountain Lion, Deer
Effects:
A. eats young trees and vegetation, leading to increased erosion
B. Pollinates Flowers, allowing new flowers to grow
C. helps keep large sized prey from growing too quickly
Butterfly - B
Mountain Lion - C
Deer - A

Identify the False sentence from the paragraph:
Matter moves from the grass to the elk and then to the wolf. When these organisms die, decomposers break down the matter in them and return it to the soil. Animals such as elk and wolves take in matter from the environment as water and air. Plants do not take in matter from the environment.
Plants do not take in matter from the environment.
