Remembering the name of an organism and describing what a structure does are different tasks. This guide moves through plants, animal structures and ecological relationships. First establish which organism or group the question concerns. Then decide whether the answer should name a process, describe a body feature, or identify a relationship among organisms.
Pay attention to words that limit the claim, such as adult and typically. A question about an adult insect does not ask for a rule about every small animal you have seen. Likewise, a question about one organism differs from a question about a sequence linking several organisms. Keep that scope visible while comparing choices.

The plant example asks for the process in which green plants use light to make organic substances. Photosynthesis links that input with the stated function. When you review the answer, retain both the name and the function rather than memorising the name alone.
The adult-insect example asks about a body plan: typically three pairs of legs, giving six legs. Say which group and life stage this count describes. Do not silently extend that statement to every animal that is small or has jointed legs.
A food chain describes a sequence linked by eating and being eaten. Multiple connected chains can form a food web. In the example, the requested term concerns the link among organisms rather than an organ inside one of them.
To review these questions, write a compact description with a subject and a verb: the plant uses light, the adult insect has the stated leg arrangement, or the organisms are connected by feeding. Then check whether your description answers the exact wording, without adding a larger claim about all living things.
