Question

what are some changes that can occur in ecosystems?

Explanation:

Ecosystems can undergo natural and human - induced changes. Natural changes include succession (primary like on bare rock, secondary after disturbance), climate - related shifts (e.g., temperature, precipitation changes affecting species distribution), and natural disasters (wildfires, floods altering habitats). Human - induced changes involve habitat destruction (deforestation, urbanization), pollution (air, water, soil pollution harming organisms), introduction of invasive species (outcompeting native species), and overexploitation (overfishing, overhunting reducing populations).

Answer:

Some changes in ecosystems are: 1. Ecological succession (primary - starting on new land; secondary - after disturbance). 2. Climate - driven changes (e.g., species range shifts due to temperature/precipitation changes). 3. Natural disasters (wildfires, floods damage habitats). 4. Human - caused habitat destruction (deforestation, urbanization). 5. Pollution (air, water, soil pollution impacts organisms). 6. Invasive species introduction (disrupt native ecosystems). 7. Overexploitation (overfishing, overhunting reduces populations).
