Do you think the spotted salamander and Elysia chlorotica completely meet the autotroph definition? Explain your response.

No

Explanation:

An autotroph is an organism that manufactures its own food all by itself. They take inorganic materials from the environment and produce organic substance which they rely on. There are two special categories of autotrophs which are: chemoautotrophs and photoautotrophs.

No

Explanation:

The spotted salamander and Elysia chlorotica must eat algae, or have algae in their bodies, to benefit from photosynthesis. They require a partnership with an autotrophic organism to have this ability. So, they don’t completely meet the definition of an autotroph.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
