1. Ecology studied at community level look at interactions between
: species
2. In most cases, species share a habitat (TRUE OR FALSE): TRUE
3. Place where an organism or a community of organisms live, including all
living and nonliving factors or conditions of surrounding environment:: habitat
4. Number of species occupying the same habitat and their relative abundance
(proportion):: species diversity
5. What are the 4 types of community interactions:: 1.Competition
2. Predation and Herbivory
3. Symbiosis (Parasitism, mutualism, commensalism)
4.Facilitation
6. Symbols or to indicate how each interspecific interaction affects
1/7
,the survival and reproduction of the two species engaged: +, -
7. competition is a ( / ) interspecific interaction: -, -
8. The sum of species' use of biotic and abiotic resources in its environment is
called " " (role of species): ecological niche
9. When two species compete for same limiting resources, they can coexist
permanently in the same place (TRUE OR FALSE): FALSE: they cannot
10. two species cannot occupy the same in a habitat
THIS IS KNOWN AS THE competitive principle: niche
- competitive exclusion principle (species cannot coexist in a community if they are competing for all the same resources)
11. How can Exclusion be avoided? What is this referred to as?: - Exclusion can be avoided
if populations evolve to use different resources, different areas, or feed at different times
- This is referred to as resource partitioning: differentiation of species niches enabling them to coexist in a community
2/7
, 12. is a ( / ) interaction between species in which one
species, the predator, kills and consumes the prey. Ex: a lion attacking an
antelope
is a ( / ) interaction in which an organism eats parts
of a plant or algae. Examples include large mammalian herbivores like cattle,
sheep. Most herbivores are invertebrates like grasshoppers and beetles. In
