What is a flood?
This biome is hot and dry with very little rainfall. Cacti and lizards live here.
What is the desert?
These structures absorb water and nutrients from the soil.
What are roots?
This is the source of all energy in a food chain.
What is the sun?
A cactus has these to store water and protect itself from predators.
What are thick stems and spines?
This event happens in forests and can destroy trees but also help new plants grow.
What is a wildfire?
This biome covers most of Earth and is home to whales, jellyfish, and coral reefs.
What is the ocean?
Plants in windy or sandy areas like the beach often have thick, waxy leaves and deep roots. What do these adaptations help with?

What is the tundra?
This type of root helps mangrove trees survive in wet, swampy environments.
What are aerial (above-ground) roots?
These organisms break down dead plants and animals and return nutrients to the soil.
What are decomposers?
Fish use these to take in oxygen from water.
What are gills?
This long period without rain causes plants to dry up and die, affecting the whole food web.
What is a drought?
This biome is warm, wet, and has the most biodiversity with animals like monkeys, frogs, and jaguars.
What is the tropical rainforest?

If all the insects in a food web died, what would most likely happen to the animals that eat them?
They would decrease because they lost their food source.
A polar bear has thick fur, a layer of fat, and white coloring. How do each of these help it survive in its environment?

When this harmful substance enters rivers and oceans, it can poison fish and hurt the entire aquatic ecosystem.
What is pollution?
This biome is flat, has few trees, and is known for grasses and grazing animals like bison and zebras.
What is the grassland?
Some plants in cold environments have dark-colored leaves and grow low to the ground. Why?
To absorb more heat and stay protected from freezing winds.
In a forest food web, if the number of deer increases a lot, what could happen to the plants they eat and the wolves that hunt them?
Plants may decrease; wolves may increase due to more food.
