What do you think invasive species means?  I think it means a ecosystem maybe has changed because of the food chain and is going to keep changing because of different animals.

What does it mean to invade something? I means get into there stuff/invade there stuff.

Can animals invade? Yes because animals invade to get food and to find there habitat.

What about plants? Yes because plants invade to grow and when they get bigger they go into the other plants space.

How might invasive species affect other organisms in their environment? It maybe will affect the food chain because if animals keep coming in and out of the food chain animals will start to die because other animals keep dying.
