Question

abundance e and distribution of organisms and the interactions between organisms and the environment B. Study of the abundance of organisms C. Study of the interactions of organisms with each other D. Study of animals and plants 2) What is a community? A. It describes how energy moves among species and the environmert K B. It describes populations of species living and interacting with each other C. It describes one species of organisms and their adaptations D. It describes the butterfly effect 3) How are most terrestrial communities characterized? A. By abiotic conditions (hot dry desert community) B. By dominant animals (potato bug and millipede community) C. By disturbances (Fire community) D. By dominant plants (oak and hickory community) 4) What is the difference between species and species diversity? A. richness includes the total number of species and relative abundance, while diversity includes only relative abundance B. diversity includes the total number of species and relative abundance, while richness the total number of species richness includes only relative abundance, while diversity includes only the total number of species D. liversity includes only relative abundance, while richness includes only the total number of species 5. What is an example of an indirect effect in a trophic cascade? A. A predator (trophic level 3) reduces B. A prey (level 2) seeks refuge to hide from a predator (level 3). C. A predator (level 3) goes extinct because it consumes all the prey (level 2) its prey population (trophic level 2) by eating them D. A predator (level 3) reduces its prey population (level 2) which allows for an increase in primary producers (level 1) 6. Why are independent species found in the same location? (choose best answer) A. They rely on one another B. They have similar abiotic requirements C. They are mutualistic D. They are commensal 7. What is community succession? A. How species interact with one another B. How communities interact in a landscape C. How communities change over time D. How communities are dependent on periodic disturbances

Explanation / Answer

6) Two independent species found in the same location becasue they have similar abiotic requirements.

7)A community succession ia a process of change in the species comprising an ecological community over a period of time. Hence the correct answer here is (c).
