Q

Community

A

Each habitat has its own community of organisms. Community is all the populations that live in the habitat. Ex, Hedgehogs, snails, foxes and primroses belong to the Woodland habitat.

Q

Interdependence

A

How organisms depend on each other for their survival, like a buttercup depend on bees and bees depend on buttercups for pollination.

Q

Ecosystem

A

All the plants and animals in an area interacting with each other and their environment. E.g desert, tropical, rainforest, grasslands, seashore. A habitat would be the woodland area in the grassland.

Q

Decomposer

A

Organisms that feed on dead plants and animals e.g earthworms, bacteria, fungi. (Decomposers are very important as they break down dead things and release lots of minerals into the soil).

Q

Competition

A

Occurs when two or more organisms seek a resource that is limited, plants compete for light, water, minerals and space. Animals compete for food, shelter, territory and mates

Q

Dandelion adaptation

A

The dandelion has a long root which means it reaches below the short root of grass to get water.
Dandelions are able to compete for space because they are able to spread their seeds in the wind.

Q

Hedgehogs adaptation

A

They have an excellent sense of smell to make them good at finding food, they have spikes to fight off predators and also have a colour that makes them camouflage so they cannot be found by predators.

Biotic factors
Are living, e.g competition, predation, symbiosis
26
