The answer is lots of things!

 

Here is a short list for you to think about - 

 

• Predators or enemies

• Lack of food and water - all living things need access to food and water.

• Lack of sunlight - even humans need sunlight to survive!

• Environmental changes - weather changes such as storms, floods or drought

• Fire - some plants require fire to help release their seeds to regenerate. 

• Pollution - this lowers the quality of our air.

• Loss of habitat
