Succession is the process of change in the biodiversity of an ecosystem over time. One type of
succession is a process that brings life into a previously uninhabited area. What type of succession is
this?
What is primary succession
Predict the consequences of a significant decrease in the decomposer population in an ecosystem
What is accumulation of dead organic matter and a decrease in nutrient recycling, leading to reduced soil fertility
Analyze how the introduction of a new species might affect the niches of existing species in an ecosystem.
It may lead to increased competition and niche shifts.
What percentage of energy from the sun is transferred to tertiary consumers?
What is .1%
How do secondary consumers differ from primary consumers in a food chain?
What is secondary consumers eat primary consumers.
What is the final stage of ecological succession in a specific climate and geography

Compare and contrast the roles of producers and decomposers in an ecosystem.
What is producers convert solar energy into chemical energy for consumers, while decomposers break down dead organisms to recycle nutrients back into the ecosystem.
