How is a food chain developed?

A food chain always starts with plant life and ends with an animal.

What is a producer?
Plants are called producers because they are able to use light energy from the Sun to produce food (sugar) from carbon dioxide and water.
What is a consumer?
Animals that eat plants and/or other animals are called consumers.
What is a herbivore?
Animals that eat ONLY plants are called herbivores (or primary consumers).

A-LEVEL PE (OCR): PAPER 3 - Ethics and Deviance in Sport

These flashcards describe key performance-enhancing methods, including blood doping—a technique used to increase red blood cell count and oxygen-carrying capacity, commonly by endurance athletes—and anabolic steroids, which boost strength, aggression, and training capacity. They highlight how these methods aim to enhance performance, often through artificial physiological manipulation.

Animal Behaviour - Applied Cat Ethology

In applied cat ethology, behavioural genetics are primarily inherited through the paternal line. This means certain behavioural traits, such as temperament or sociability, can be strongly influenced by the genetics of the sire (father).

TermDefinition
What is the difference between a food web and a food chain?
A food web shows how plants and animals are connected in many ways to help them survive, while a food chain follows just one path as animals find food.

Where do animals get the energy they need and why do they need the energy?

You get energy from the food you eat. Similarity, all living things get energy from their food so that they can move and grow. As food passes through the body, some of it is digested. This process of digestion releases energy.

How is a food chain developed?

A food chain always starts with plant life and ends with an animal.

What is a producer?
Plants are called producers because they are able to use light energy from the Sun to produce food (sugar) from carbon dioxide and water.
What is a consumer?
Animals that eat plants and/or other animals are called consumers.
What is a herbivore?
Animals that eat ONLY plants are called herbivores (or primary consumers).
What is a carnivore?
Animals that eat OTHER ANIMALS are called carnivores.

What is a secondary consumer?

Carnivores that eat other carnivores are called tertiary consumers. For example, killer whales in an ocean food web-->phytoplankton-->small fishes-->seals-->killer whales

What is a tertiary consumer?
Carnivores that eat other carnivores are called tertiary consumers.
What is an omnivore?
Animals and people who eat BOTH animals and plants are called omnivores.
What is a decomposer?
Decomposers (bacteria and fungi) feed on decaying matter.
What happens in a food chain?
In a food chain, energy is passed from one link to another.
What happens to the amount of energy in a food chain?
The amount of energy in a food chain decreases as you move along it.
How many links are in a food chain?
Most food chains have no more than four or five links.
Why can't there be too many links in a food chain?
There cannot be too many links in a food chain because the animals at the end of the chain would not get enough food (and hence energy) to stay alive.
What makes a food web?
Most animals are part of more than one food chain and eat more than one kind of food, forming a food web.
What can you substitute the arrows in a food chain or web by?
Arrows in a food chain or web can be substituted with the words 'eaten by'.
