Food Webs Flashcards

1️⃣ Familiarise yourself with the flashcards:

Look through all the flashcards to see what's on both sides.
Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

Look at the question or prompt on each card and try to remember the answer before flipping it over.
Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

What is a food web?

A food web is a diagram that shows how many food chains link together in one habitat.

A food chain shows one path of energy, but a food web shows many linked paths between lots of plants and animals.

A producer is a green plant or alga that makes its own food by photosynthesis and is eaten by other organisms.

A consumer is an animal that gets its energy by eating plants or other animals.

A predator is an animal that hunts and eats other animals. The animals it eats are called its prey.

The same animal can eat different foods and be eaten by different predators, so it is part of several linked food chains.

An omnivore is an animal that eats both plants and animals, so it links many parts of the food web.

If one species is removed, its predators may have less food and its prey may increase, changing the numbers of many organisms.

If prey numbers fall, predators may starve, move away or die, so their numbers also fall.

Pollution or habitat loss can kill or remove some species, which then changes the numbers and links of other organisms in the food web.
