Every organism has certain features or characteristics that allow it to live successfully in its habitat. These features are called adaptations, and we say that the organism is adapted to its habitat. Organisms within a community compete with each other for limited resources, including water and space. Plants also compete with each other for light and minerals.

Different adaptations

Organisms live in different habitats need different adaptations. Animals and plants may have specific features that adapt them to their environment: these include barbs and spines, poisons and warning colours that deter predators and herbivores. Some harmless species may even resemble a poisonous or dangerous species to increase their chances of survival.

Branches and leaves: bees, wasps, moths, squirrels, bluetits and hawks. Trunk: insects and larvae. Root and litter zone: bacteria, earthworms, wood lice and fungi.
