Question

1. which of the following would be impacted the most in an ecosystem if the decomposer population was greatly reduced?

a. predation in the environment would decrease.
b. nutrient recycling in the environment would decrease.
c. oxygen in the air of the environment would increase.
d. reproduction rates of the producers in the environment would increase.

1. a food web shows the interaction of organisms in an ecosystem. which statement best describes the transfer of energy in a food web?

a. the amount of energy transferred at each trophic level decreases because some is lost as heat.
b. the amount of energy transferred at each trophic level is the same because energy is conserved.
c. the amount of energy transferred in each trophic level increases because the size of the organisms increases.
d. the amount of energy transferred at each trophic level is different in land and marine ecosystems because the animals are different.

Explanation:

Decomposers play a crucial role in nutrient cycling. They break down dead organisms and waste materials, releasing nutrients back into the environment. If the decomposer population is reduced, the recycling of nutrients would be affected. Predation affects the population of predators and prey. Oxygen in the air is mainly related to photosynthesis (by producers) and respiration. Reproduction rates of producers affect the producer population size.

Answer:

B. Nutrient recycling in the environment would decrease.
