Answer 2

Answer:

The required answer is Option (a) Food chain

Explanation

A food chain is a series of organisms that pass nutrients and energy from one to the next as one eats another. Let's take a look at the various components of a typical food chain, beginning at the bottom (the producers) and working our way up.

• The primary producers are at the bottom of the food chain. Autotrophs are primary producers, which are usually photosynthetic organisms like plants, algae, or cyanobacteria.
• Primary consumers are organisms that eat the primary producers. Herbivores, or plant eaters, are the most common primary consumers, though algae eaters and bacteria eaters are also common.
• Secondary consumers are organisms that eat the primary consumers. Carnivores—meat-eaters—make up the majority of secondary consumers.
• Tertiary consumers are organisms that eat the secondary consumers. These are carnivores that eat other carnivores, such as eagles or large fish.
• There are additional levels in some food chains, such as quaternary consumers, which are carnivores that eat tertiary consumers. Apex consumers are organisms at the very top of a food chain.
