Based on what you have learned about Habitats 1, 2, and 3, fill out the food web below by drawing lines connecting the animals to what they eat.
Food Web
In coral reefs, tiger sharks eat guard crabs and parrotfish. Draw a box where tiger sharks should be in the food web and connect it to what it eats.
While the animals in some of the habitats seemed to eat up a food source, these food sources would be expected to grow back over time (as long as they were there to start with). Having the same species of plants and animals in an area for a long time would make the habitat ____________________.
Which species do you think would be found in each habitat after one year? Habitat 1: algae coral seagrass guard crabs sea snails parrotfish Habitat 2: algae coral seagrass guard crabs sea snails parrotfish Habitat 3: algae coral seagrass guard crabs sea snails parrotfish

Guard Crab

Sea Snail

Parrotfish

Algae

Coral

Seagrass

Part 3: Hungry Habitats — High Temperatures
