SUBJECT: BASIC ECOLOGICAL CONCEPTS
CONCEPT:
Sub–Topic 1: ECOLOGICAL CONCEPTS
Ecology is the study of living organisms in relation to their environment.
The study deals with the relationship of living organisms with one another and with the environment in which they live. Ecology measures factors affecting the environment; it studies the distribution of living organisms and how they depend on one another and their non-living environment for their survival.
Ecology is divided into two
(i) Autecology which is the study of a single individual organism or a single species of organism and their environment. E.g. the study of Tilapia fish in a particular stream.
(ii) Synecology which is the study of inter–relationships between groups of organisms or species of organisms living together in an area. E.g. the study of all organisms in a particular stream in relation to their environment.
Ecology Concepts
Environment: This refers to all the factors in an organism’s surroundings, living or non-living. The factors include the place where the organism lives and the physical conditions in the place, the food, water and air it takes in, the animals that prey on it and the disease that affect it.
Habitat: This is the place where an organism lives. It is the place that is suitable to the organism’s way of life e.g. the habitat of fish is water.
Examples of habitats include:
