                          Adaptation and Competition notes

What you need to know:

a) Know that organisms that have similar features and characteristics can be classified together in a logical way. Understand the need for a scientific system for identification and scientific as opposed to ‘common’ names.

b) Use data to compare the variety of organisms which live in particular habitats; investigate how the organisms in an area are affected by other organisms.

c) Explore information about the structure of an organism and how they are adapted to survive in their environment.

d) Know that individuals have a basic need for energy and resources from their environment and that the size of a population of individuals may be affected by competition, for food, space, light; predators, disease, pollution and availability of minerals.

e) Examine how indicator species, changes in pH and oxygen levels may be used as signs of pollution in a stream and the examination of lichens as indicators of air pollution.  

Classification means putting things into groups. Classification helps scientists make the understanding of living things more manageable and help them understand the relationship and trends between living things.
