Match the cause and effect of natural disruptions

• Food chain can break

• Too few animals

• Not enough food for others, hurts food w

• Organisms die or move away

• Increase in food-intake, hurts food web

• Too many animals

NGSS.MS-LS2-4

Match the cause and effect of human disruptions to ecosystem

• Overfishing

• Organisms die or move away; less food for other trophic levels

• No Habitat for Organism to live

• Food becomes unsafe or dies out; leaves no food for other trophic levels

• Pollution

• Reduces food available for predators
