Official JAMB Biology outline · C: Ecology
Content
Symbiotic and ecological interactions: parasitism, saprophytism, commensalism, mutualism, amensalism, competition, predation and cooperation.
Objective
Provide appropriate examples of symbiosis, parasitism, saprophytism, commensalism, mutualism, amensalism, competition, predation and cooperation among organisms.
Content
Energy flow in ecosystems: food chains, food webs and trophic levels; distribution of organisms in particular habitats.
Objective
Explain the distribution of organisms using food chains and food webs; define food chains and food webs.
Content
Nutrient cycles in nature: carbon cycle, water cycle and nitrogen cycle; balance of atmospheric oxygen and carbon(IV) oxide; global warming; roles of bacteria and leguminous plants in nitrogen cycling.
Objective
Describe the carbon cycle and its significance; explain the balance of atmospheric oxygen and carbon(IV) oxide and the relationship with global warming; assess the effects of the water cycle on other nutrient cycles; relate the roles of bacteria and leguminous plants to nitrogen cycling.
