Based on the table, native organisms will be negatively affected by competition with lionfish if they-
hunt in fresh water.
live on land.
are longer than 45 centimeters.
eat invertebrates.
One explanation for the increasing wild hog population is -
they are able to escape hunters.
other wildlife populations have been reduced.
food supplies have increased across the state.
they are able to survive in a variety of environments.
There are three species of birds on an island. Bird A has a pointed bill for eating insects. Bird B has a heavy bill for eating seeds. Bird C has a sharp bill for eating seeds and insects. If the insect populations suddenly disappeared one season, which bird would probably be the least affected that season?
Bird A
Bird B
Bird C
Bird B and Bird C

During ecological succession, why do grasses appear before shrubs?
Because grasses provide food for animals returning to the area.
Because grasses require plenty of sunlight to make their own food.
Because grasses loosen the dirt for new trees to take root.
Because grasses can grow rapidly even in an area with shallow soil.
After a catastrophic wildfire that clears the land of all plants and trees-
plants will not grow again in the burned area.
weeds will grow in the area before trees grow.
bushes will grow in the area before weeds grow.
only trees will grow in the burned area.
