which is not an impact of global warming on ecosystems

population explosion among various species

warmer weather causes some species to migrate out of their natural habitat in search of cooler temperatures

certain species face extinction

food supply increases***

I just put that as my answer and it was correct so...

The correct answer is "food supply increases."

To determine the impact of global warming on ecosystems, we need to analyze each option and understand its relationship to global warming.

1. Population explosion among various species: This is a possible impact of global warming. As temperatures rise, it can lead to increased reproduction rates, resulting in the population explosion of certain species.

2. Warmer weather causes some species to migrate out of their natural habitat in search of cooler temperatures: This is also a possible impact of global warming. Some species may be unable to adapt to the higher temperatures, causing them to migrate to cooler regions. This disrupts their natural habitat and can affect the balance of ecosystems.

3. Certain species face extinction: This is a well-documented impact of global warming. As temperatures continue to rise, it can disrupt ecosystems, impacting the survival and reproductive abilities of various species, ultimately leading to their extinction.

4. Food supply increases: This option does not align with the impacts of global warming. The increasing temperatures and changes in ecosystems often lead to a decline in food supply rather than an increase. Climate change can negatively affect agriculture, fisheries, and overall food production, leading to food shortages and challenges in food security.

Therefore, the correct answer is "food supply increases" as it does not align with the commonly observed impacts of global warming on ecosystems.

NO.
