Write a paragraph (5-8 complete sentences) answering the prompt＂How does the availability of resources in ecosystems impact ecosystems?＂

Answers

5-8 Sentences on: "How Does The Availability Of Resources In Ecosystems Impact Ecosystems?"

Changing out natural resources in our environment can affect the whole entire ecosystem.  Ecosystems can change throughout time but the change may or may not affect the ecosystems.  But according to research, if the change is too fast the whole ecosystem can be destroyed.  An imbalanced or damaged ecosystem can lead to problems.  Certain resources play an important role such as sunlight and water, we need resources to survive and can also help living creatures.  These resources impact animals, plants, and insects/bugs.
