APPLYING CONCEPTS
100
These zones receive the sun’s rays at a very low angle. (88)
What is polar zones
100
When one member benefits and the other is neither helped nor harmed, it is called this. (93)
What is commensalism
100
This Biome is primarily characterized as a dry biome. (101)
What is The desert
100
13. The depth, flow, temperature, and chemistry of their water characterize These biomes. (106)
What are Aquatic biomes. (106)
100
This is a large complex of communities with certain soil and climate conditions. (98)
What is A biome
200
This gas and water vapor are greenhouse gases that trap heat energy in the atmosphere. (87)
What is Carbon dioxide
200
This occurs on surfaces where no soil exists, such as after a volcanic eruption. (95)
What is Primary succession
200
Trees that produce seed-bearing cones and have needle-like leaves are called this. (103)
What is Coniferous Trees
200
This zone is the dark region of the ocean where photosynthesis cannot occur. (109)
What is aphotic
200
A relationship where two species benefit one another is called this. (93)
What is mutualism
300
This zone is the region near the equator. (88)
What is tropical Zone
300
This is when one organism lives on or inside another organism and harms it. (93)
What is Parasitism
300
The tundra is the coldest biome, characterized by this, a layer of permanently frozen subsoil. (104)
What is Permafrost
300
This zone is the well-lit upper layer of a body of water where photosynthesis can occur. (109)
What is Photic zone
300
A plant or animal that can survive and reproduce in non-optimal conditions exhibits this. (98)
What is tolerance
400
18. Generally, this coasts receives cold currents, and east coasts receive warm currents. (89)
What is West Coast
400
14. One species wiping out a rival with the same niche and habitat is an example of this. (92)
What is the competitive exclusion principle
400
This Biome, also known as the taiga, is characterized by evergreen coniferous trees. (104)
What is Boreal Forest
400
These are unicellular algae that form the base of many food webs for aquatic ecosystems. (107)
What is Phytoplankton
400
24. Earth’s climate zones are affected by differences in this but not differences in altitude. (89)
What is Lattitude
500
These zones sit between the polar zones and the tropics. (89)
What is Temperate
500
When an ecosystem is disturbed, this occurs and restores the ecosystem to balance. (95)
What is secondary succession
500
This Biome has year-round rainfall and a dense covering of tall trees called the canopy. (100)
What is The tropical rain forest
500
This ecosystem is made up of warm shallow waters of tropical coastal oceans. (111)
What are Coral Reefs
500
A food web demonstrates the community interactions of this and predation. (92-93)
What is competition
