Anew species is discovered and scientists are trying to classify it. one of the key features found is that the species is entirely dependent on other organisms for its food necessary to sustain life. what type of species is this? a. autotrophic b. mixotrophic c. producer d. heterotrophic

Option D

Explanation: The organism that cannot synthesize their own food are kept in the category of heterotrophs. These organism derive their energy from the organism that make food.

These organisms lack the ability of making food by the help of the process  photosynthesis. They lack the pigment required for this process.

These kinds of organisms are termed as Heterotrophic organism.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
