is anyone able to help me revise for my biology exam coming up soon? This is what I need to know

Population Community Ecosystem biotic abiotic
Habitat Tolerance range Canopy Climax community Symbiotic
Niche Zonation Epiphyte Primary succession Mutualism
Law of Tolerance Succession Stratification Secondary succession Commensalism
Law of minimum Littoral zone pioneer competition Parasitism
Carbon cycle Legume   Producer Autotroph
Nitrogen cycle nitrite Nitrate Consumer Trophic level
Nitrifying photosynthesis energy heterotroph Herbivore
Decomposer Pyramid of numbers Pyramid of energy Population density Carnivore
detritivore Pyramid of biomass Population distribution Survivorship curves Omnivore
K strategist R-strategist Carrying capacity Density dependent Density independent
The student should be able to:
· Describe a range of biotic features
· Describe a range of abiotic features
· Explain how the Law of tolerance and law of minimum can impact on an animal’s range
· Use the above concepts to answer questions about where animals might be found
· Compare and contrast zonation and succession
· Explain the process of succession
· Compare and contrast primary and secondary succession
· Compare and contrast pioneer and climax communities
· Identify relationships between different species as either mutualistic, commensal or parasitic
· Interpret data to identify predator prey relationships
· Apply the Law of conservation of energy and law of conservation of matter to ecological issues
· Discuss energy flow through the ecosystem
· Use the 10% rule to explain feeding relationships in an ecosystem
· Relate the 10% rule to the concept of bioaccumulation
· Know and interpret data on the carbon and nitrogen cycles
· Interpret information to draw a food web in the prescribed manner
· Explain the difference between the 3 different types of ecological pyramids and the reasons why all three might be necessary
· Interpret ecological pyramids
· Explain the impact of different features of populations such as distribution patterns, density, age and gender structure
· Use the capture/recapture model to estimate population size
· Discuss possible problems with the capture/recapture technique
· Interpret survivorship curves
· Know the features of organisms represented by the different survivorship curves
· Relate survivorship curve with reproductive strategy
· Describe the features of k and r strategists
· Explain the significance of the carrying capacity
· Relate carrying capacity to reproductive strategies
· Explain the population growth curve
· Compare and contrast density dependent and density independent factors and the impact they can have on populations.
· Give examples of density dependent and density independent factors
· Discuss the impact of births, deaths, immigration and emigration of population size
Relate ecological issues to human populations

That is a lot of information. As I believe I've mentioned to you before, it's hard for us to give you advice on such broad rubrics. Since I study nitrogen, I can babble for ages about the nitrogen cycle, but I have no way of knowing what your teacher wants you to know. Homework help isn't our primary focus, so I again suggest that your classmates and teachers may be more helpful.

You might get better response if you post some specific example problems or concepts you don't understand as opposed to a long study guide. Good luck on your exam! :)
