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.
