    • Keywords
      • Environment
        • all the conditions that surround any living organism - both the other living things and the non-living things or physical surroundings
      • Habitat
        • a place where plants and animals live eg a pond
      • Population
        • all the members of a single species that live in a habitat eg minnows
      • Community of living things
        • all the populations of different organisms living together in a habitat
      • Ecosystem
        • a community of animals, plants and micro-organisms, together with the habitat where they live
    • Examples of ecosystems
      • A pond ecosystem may consist of a pond habitat, inhabited by of aquatic plants, waterside plants, micro-organisms - in the mud at the bottom of the pond - minnows and herons. The organisms together make up a community of living things.
      • A woodland ecosystem The diagram shows an oak tree ecosystem. Note that different living things inhabit different zones or layers from the bottom to the top: ·         First there is the zone of roots, soil and leaf-litter beneath the tree. Here decomposers such as bacteria, woodlice, and earthworms feed off last year's leaves and acorns, and fungi grow on its roots. ·         Next is the trunk layer, which provides shelter or food to insects, caterpillars and larvae. ·         Finally comes the branches, leaves and canopy. In this zone bees gather pollen and nectar, fungi grow on the leaves, gall wasps and moths lay their eggs, and squirrels gather acorns. Small birds such as blue**** hunt the moth larvae; and sparrowhawks hunt the small birds. Each zone of this oak tree is home to a distinctive community of organisms. Each of the organisms in this ecosystem has a particular way of fitting into the oak tree environment - they each occupy a niche within the ecosystem. For example the blue **** and the squirrels, though they both inhabit the same tree, do not directly compete for food: the squirrels feed on acorns, while the **** feed on moth larvae. The two species occupy different niches within the oak ecosystem.  
    • Euglena is a single-celled organism that can move like an animal but contains chloroplasts like a plant. It is difficult to classify.
