1. What were the biotic and abiotic factors in the ecosystem?
2. List the populations in the ecosystem. Which population was the largest? The smallest?
3. Describe one niche in the ecosystem.

A. niches and habitats
B. competition
C. biotic and abiotic factors

i forgot my biology book at school and i need help with these questions. any answer helps, i prefer complete sentence if you are willing, but if not, thanks anyway. so here are the questions.
1 What is ecology?
2 define: species; population; community; ecosystem; biome; biosphere;
Tell how these are related.
3 How is a habitat different from a niche;
4 What are biotic and abiotic factors?
5 What is the Competitive Exclusion Principle?
6 How is the movement of matter AND energy through an ecosystem different?
7 What are autotrophs? Give examples. What are heterotrophs? Give examples.
8 Name two ways autotrophic organisms can make their own food. How are these different?
9 What is a resource? A food chain? A food web? How are these related?
10 What is an herbivore, carnivore, omnivore, detritivore, decomposer,scavenger?
11 How do they get their energy? Be able to give examples of each of these.
12 What is a trophic level? What percentage of energy is passed on from one trophic level to the next?
13 What is a biogeochemical cycle?.
14 How do (water, carbon, nitrogen, phosphorus) atoms enter and leave the atmosphere, land, water, and cycle through the ecosystem?
15 In which cycle does the atmosphere NOT play a role?
16 Which biomolecules are important to living things and which cycles provide the atoms to build these?
17 What is transpiration? Nitrogen fixation? Denitrification? Evaporation? Condensation? Precipitation?
18 Which organisms play a role in these processes?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~…
19 NAME the 6 levels or organization that ecologists use
20 What are the ways organisms interact in an ecosystem? Define:(Competition, Predation, Symbiosis)
21 Name the 3 kinds of symbiosis? Identify examples of each?
21 What are some things organisms must compete for?
22 What is a limiting factor? How does it affect a population?
23 What is primary productivity? An algal bloom?
24 What happens when an over abundance of a limiting factor becomes available?
25 How do organisms cooperate? What is predation? What is a predator? Prey?
26 What are the 3 kinds of symbiosis? Be able to identify examples of each?
27. Name the two things that can affect the size of a population
28. What is exponential growth? Under what conditions does it occur in a population?
29. What is logistic growth?
30. Give two examples of density-dependent limiting factors? What does this type of limiting factor
rely on?
31. What is the difference between primary and secondary succession?
32. What kind of growth is represented by a S curve (as opposed to a J curve)
33. Explain the difference between a resource that is renewable and nonrenewable.
you do not have to answer all of them (you’d be AWSOME if you did though(: ) but try to answer one that hasnt been answered yet. THANK YOU!(:
