3. both benefit (bee and a flower)
81. Define these types of relationships (symbiosis). a. mutualism – b. commensalism – c. parasitism – d. predator/prey – e. competition –
both benefit (bee and a flower)
One benefits, the other is unaffected
(bird’s nest in a tree)
One benefits, the other is harmed (tick and a dog)
Predator hunts prey
Two organisms fighting for similar resources

4. 82. What is carrying capacity?
The maximum amount of individuals in a population that the surrounding environment can sustain

7. Ecological succession
106.
This picture is showing primary succession because it begins with bare rock. Secondary succession has soil layer already in place.

8. Ecological succession
Pioneer species are the first species to inhabit an area
Ex: Lichens, Moss, bacteria

9. Ecological Succession
The climax community is the final community in which all the populations are stable and unchanging
This stage will have the most diverse of species
