In an ecosystem, what would likely occur if there were no decomposers present?
A
Herbivore populations would increase due to more plant growth.
B
Nutrient cycling would be disrupted, leading to accumulation of dead organic matter.
C
Primary producers would increase due to more available nutrients.
D
Predator populations would decrease due to lack of prey.
Verified step by step guidance1
Understand the role of decomposers in an ecosystem: Decomposers, such as bacteria and fungi, break down dead organic matter, recycling nutrients back into the ecosystem.
Consider the impact on nutrient cycling: Without decomposers, nutrients from dead organisms would not be returned to the soil, disrupting the nutrient cycle.
Analyze the accumulation of dead organic matter: Without decomposition, dead plants and animals would accumulate, leading to a buildup of organic matter.
Evaluate the effect on primary producers: Primary producers rely on nutrients recycled by decomposers. Without nutrient recycling, their growth would be limited.
Assess the impact on other trophic levels: The disruption in nutrient cycling would affect herbivores and predators, as plant growth and prey availability would be impacted.
