Subtitle

All living things have to get nutrition to stay alive. NUTRITION includes energy (from glucose which is a sugar) and nutrients (vitamins and minerals like Vitamin C and iron).

Plants are special because they can make their own glucose by doing photosynthesis. Plants are called PRODUCERS because they can produce their own food. This is important as animals need this food to eat (and we need oxygen - also made by plants).

Animals can’t make their own food. They have to consume plants and other animals. Because of this animals are called CONSUMERS.

There are different types of consumers:

HERBIVORES: consume plant material, including leaves and fruit.
CARNIVORES: consume animal material, including eggs and meat.
OMNIVORES: consume both plant and animal material.
DECOMPOSERS: consume dead plants and animals.

Examples of HERBIVORES are sheep, rabbits, kākāpō and the extinct moa.

It’s not just leaves that herbivores eat. Anything that comes from a plant can be consumed. Fruit, nectar from flowers, seeds and wood are all eaten by different herbivores.

There are different types of carnivores. One type are called predators, which hunt, kill and eat animals for their food (prey). Examples include cats and wolves. The native New Zealand snail (Powelliphanta) is an unusual snail as it is a carnivore, sucking up earthworms like spaghetti!

Carnivores that find already dead animals and eat them are called scavengers, for example hyena and vultures.

Consumers that eat both plants and animals are called omnivores. For example rats, humans, chickens and pigs are omnivores.

Consumers that break down dead plants and animals are called decomposers, for example worms.
