Which physical factors MOST influence a marine biome? (HINT: Water is the largest aspect of this biome.)

• tides, oxygen, costal hotel development

• sunlight, fishing boats, whale population

• wave motion, salinity, atmospheric pressure

• plankton, water temperature, sand composition

Answer explanation

Wave motion, salinity, and atmospheric pressure most influence a marine biome. The characteristics of the water most directly effect all the organisms living in and around it. Physical factors are non-living.

The small mammals, insects, and plants living in the tundra cannot migrate to warmer places to avoid the severe winter conditions. They have very specific adaptive strategies for survival. Identify the adaptation and purpose that is not seen among tundra plants. (HINT: Not an advantage to plant growth.)

• Low growing plants to avoid the drying winds.

• Waxy coating prevents evaporative water loss.

• Tundra plants can only photosynthesize in bright light.

• Silver-gray hairs on leaves provide a greenhouse effect so plants stay warm.

Answer explanation

Tundra plants can only photosynthesize in bright light. First, this is not an advantage. Second, it is not true. Tundra plants can photosynthesize in various conditions, including low light an low temperatures.

Which of the following is a characteristic of all biomes?

• They all have the same temperature and precipitation levels.

• They are unaffected by human activities.

• They each have unique physical characteristics, climates, and species.

• They are all located at the equator.

This aquarium exhibits biotic and abiotic factors in an aquatic environment. One of the abiotic factors is (HINT: Biotic factors exhibit living characteristics)

• coral.

• fish.

• plants.

• water.

Answer explanation

The answer is water. This is because abiotic means not living.

A biome is...

• a large region with a specific climate and certain types of plants/animals

• a cone-bearing tree

• the animals living in the region

• a body of water

match the Biome with it's correct definition. Desert

• Extremely dry; very low precipitation

• Extremely cold; permafrost in the soil

• Mild; has four seasons

Match the Biome with it's correct definition.

• Found in the North; has cone-bearing trees and long winters

• A grassland with large herbivores

• Makes up over 70% of Earth's surface

Rivers, lakes, streams, and ponds are...

• freshwater, as they contain salt.

• saltwater, as they cotain salt.

• freshwater, as they don't contain salt.

• saltwater, as they don't cotain salt.
