6) This is a food web for a small forest ecosystem. Suppose that a farmer near the forest sprayed crops with a pesticide to kill insects and that some of the spray washed into nearby streams and groundwater Food webs are complex and a change in one species would likely cause a change in other species as
well. Which of these species is LEAST likely to be affected by nearby pesticides?
A) mice
1) toads
snakes
D) insectivorous birds

This is a typical grassland food web. it is also a small picture of an important cycle on earth: the carbon cycle. describe how the carbon gets into this food web. a) bacteria and fungi, the decomposers, recycle carbon from dead organisms. b) carbon is found in the grass and is passed from one level to the next in this food web. eliminate c) all living things give off carbon dioxide as a by-product of respiration and it is released into the atmosphere. d) plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar.
