What could cause a decrease in the number of producers in an ecosystem Primary consumers Secondary consumers?

A decrease in the number of producers in an ecosystem can be caused by factors such as habitat destruction, pollution, climate change, or invasive species, which can negatively impact plant growth and survival. With fewer producers, primary consumers may struggle to find adequate food sources, leading to a decline in their populations. This, in turn, affects secondary consumers that rely on primary consumers for energy, creating a ripple effect throughout the food web and disrupting ecosystem balance.
