1.   The biotic features of an ecosystem include all the l__________ o__________.
2.   The a__________ features of an ecosystem include the non-living things such as
     t__________, w__________, l__________ and o__________.
3.   E__________ is the study of the interaction of organisms with each other and
     the environment.
4.   In an e__________, organisms interact with each other in a balanced way.
5.   C__________ is the management of resources to protect the Earth’s natural
     resources.
6.   Water can exist in all three states, i.e. s__________, l__________ and
     g__________.
7.   The water on Earth moves through a cycle from the e__________ of oceans and
     other water bodies, to the a__________ and back to the land and used for living
     things via the r__________.
8.   The great variety of living things is called b__________.
9.   Humans are affecting the biodiversity by causing loss of habitat through
     activities such as f__________, m__________, building c__________, using
     p__________ for control of pests in agriculture and by adding introduced
     s__________ e.g. the rabbit, which may compete with native species for food.
10. The clearing of land for agriculture has also caused huge problems such as
    e__________ along river banks and gullies.
11. The element c__________, which is present in all living things, is cycled
    through nature particularly via the processes of r__________, p__________ and
    d__________ of dead organisms.
12. The process of making food in plants from water and carbon dioxide in the
    presence of sunlight and chlorophyll (the green pigment in plants) is called
    p__________.
13. R__________ is the chemical process that occurs in all cells of living things
    involving the breakdown of food (glucose) in the presence of o__________ to
    produce energy.
14. D__________ involves the breakdown of dead organisms by bacteria and
    f__________.
