Question

lesson activities: hs ls2-1, hs ls2-2 - september 08 - do now / warm up question (monday tuesday) organisms that are dependent on other organisms for survival, • autotrophs • heterotrophs • decomposers • all answers are correct

Explanation:

To determine the correct answer, we analyze the definitions:

• Autotrophs: Organisms that produce their own food (e.g., plants via photosynthesis) and are not dependent on other organisms for food (though they may depend on other factors like sunlight, water, etc., but the question is about dependence on other organisms for survival in terms of obtaining nutrients).
• Heterotrophs: Organisms that cannot produce their own food and must consume other organisms (or organic matter) for energy and nutrients. So they are dependent on other organisms for survival (for food).
• Decomposers: They break down dead organic matter (from other organisms) and are dependent on other organisms (the dead ones) for their energy source. But let's re - evaluate the options. Wait, the question is "Organisms that are dependent on other organisms for survival".

Wait, actually, autotrophs make their own food, so they are not dependent on other organisms for food (a key aspect of survival - getting energy/nutrients). Heterotrophs need to eat other organisms (or their products) to survive. Decomposers break down dead organisms, so they are dependent on the dead organisms (which were once living) for their energy. But the option "Heterotrophs" is the most direct answer as heterotrophs (like animals, fungi that are not decomposers in the strictest sense of breaking down dead matter, etc.) rely on living or recently living organisms for food. Wait, but decomposers also rely on other organisms (dead ones). However, the standard answer for this type of question is usually Heterotrophs. Wait, let's check again:

• Autotrophs: Self - feeding, so not dependent on other organisms for food (the main way they survive - getting energy).
• Heterotrophs: Rely on other organisms (either living or dead, but in the context of "dependent on other organisms for survival" in terms of nutrition, heterotrophs are organisms that must consume other organisms (or organic compounds from other organisms) to live.
• Decomposers: They break down dead organic material, so they are dependent on the dead organisms (which are other organisms) for their energy. But the option "Heterotrophs" is more commonly the answer to this type of question as decomposers are a type of heterotroph in some classifications, but the main distinction is autotroph (self - feed) vs heterotroph (feed on others). So the correct option is Heterotrophs.

Answer:

B. Heterotrophs (assuming the options are labeled as A. Autotrophs, B. Heterotrophs, C. Decomposers, D. All answers are correct)
