Answer 2

Answer:

Key points:

Producers, or autotrophs, make their own organic molecules. Consumers, or heterotrophs, get organic molecules by eating other organisms.

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain.

Food webs consist of many interconnected food chains and are more realistic representation of consumption relationships in ecosystems.

Energy transfer between trophic levels is inefficient (with a typical efficiency around 10\%10%10, percent). This inefficiency limits the length of food chains.

Organisms of different species can interact in many ways. They can compete, or they can be symbionts (long-term partners with a close association). Or, of course, they can do what we so often see in nature programs: one of them can eat the other.

What basic strategies do organisms use to get food? Some organisms, called autotrophs (“self-feeders”), can make their own food – that is, their own organic compounds – out of simple molecules like carbon dioxide. There are two basic types of autotrophs:

Photoautotrophs, such as plants, use energy from sunlight to make organic compounds (sugars) out of carbon dioxide in photosynthesis. Other examples of photoautotrophs include algae and cyanobacteria.

Chemoautotrophs use energy from chemicals to build organic compounds out of carbon dioxide (or similar molecules). This is called chemosynthesis. For instance, there are hydrogen sulfide-oxidizing chemoautotrophic bacteria found in undersea vent communities (where no light can reach).
