Food Chain Hide and Seek
OBJECTIVES:
Students will learn:
• The basic interactions between consumers in a food chain (predation, competition).
• The number of damselfish in an area can influence how many
damselfish die due to predation, termed
density-dependence.
• Pollution decreases the amount of coral habitat available for shelter, which will contribute to the number of damselfish
that die due to predation.

Connected Ecosystems
OBJECTIVES:
Students will learn:
• Ecosystems are made of animals and plants (biotic) working together with the abiotic (non-living) components of their habitat, such as light, temperature, food, and shelter.
• Interactions with both the living and non-living components of an organism's ecosystem are essential for an organism's survival.
• Natural ecosystems go through cycles, which can be altered by natural and human-induced disturbance.
