Question

is 1: ecosystem interactions & energy summative assessment review

1. if the ecosystem experienced a severe drought which organisms would be the most affected?

a. the bird
b. the badger
c. the flower and grass
d. the bee, grasshopper, and prairie dog

1. which species has reached its carrying capacity first?

a. species 1
b. species 2
c. species 3
d. species 4

Explanation:

For question 1:

• Producers (like flowers and grass) are the base of the food - web. A drought would directly affect their photosynthesis and survival as they need water for basic metabolic processes.
• Consumers (birds, badgers, bees, grasshoppers, prairie dogs) depend on producers. If producers are affected, consumers will be affected later through food scarcity.

For question 2:

• Carrying capacity is the maximum number of organisms an environment can support.
• Looking at the graph, Species 4 levels off (reaches a relatively stable population) earliest compared to Species 1, 2, and 3.

Answer:

1. C. The flower and grass
2. D. Species 4
