C) Grasshopper, Birds, Hawks
28
What energy transformation takes place in photosynthesis?
Solar energy is converted into chemical energy
29
What is most likely to happen to the population of predators in the future?
The population of predators will increase
30

B) Fox and Snake
33
What is a correct flow of energy in typical food web?
Sunlight-Producer-Herbivore-Carnivore
34
What is the largest level of organization in an ecosystem?
D) Community
35
How is a population different from a community?
A population is made up of all members of the same species living in the same area, while a community is made up of all populations living in the same area
36
What's the difference between a primary consumer and secondary consumer?
Primary Consumers eat producers, Secondary Consumers eat Primary Consumers
37
What biotic factors might the predators compete for?
Primary & Secondary Consumers
38
What abiotic factors might the predators compete for?
Water
39
What might happen to the level of competition if the level of resources decreased?
It will increase because resources are hard to get
40
What might happen to the predators if this change in resources occurred?
Most likely die because resources become extinct
41
What are the most accurate biotic and abiotic factors in an ecosystem?
``` Biotic: -Producer -Consumer -Decomposer Abiotic: -Soil -Air -Sunlight ```
42

C) Bacteria
44
Parasites coat the skin of the ocean sunfish, also called the Mola mola. Sometimes the MM will lie on its side in the ocean and allow seabirds to remove external parasites. The parasites are a source of food for the seabirds. The relationship between the mola mola and seabirds is an example of..
