please don't just tell me to do my homework... I just need some help. Biology doesn't make any sense to me. Thank you so much!
1.What term describes the give and take between the biosphere and Earth's other spheres?
A.biota
B.feedback loop
C.Gaia loop
D.photosynthesis
2.How are the biosphere and biota related?
A.Biota are the living things that inhabit the biosphere.
B.The biosphere is part of the biota.
C.Both the biota and the biosphere are part of the hydrosphere.
D.Both the biota and the biosphere are part of the geosphere.
3.Which Earth system includes everything below Earth's surface?
A.hydrosphere
B.geosphere
C.biosphere
D.atmosphere
4.What does the Gaia hypothesis explain?
A.how plants increase the level of carbon dioxide in the atmosphere
B.how feedback loops affect the process of photosynthesis
C.how biotic and abiotic factors interact in the biosphere
D.how Earth's spheres are independent of each other
5.Which of Earth's systems are humans a part of?
A.The hydrosphere
B.The part of the biosphere that doesn't include the biota
C.The biota portion of the biosphere
D.atmosphere
6.What determines Earth's climate zones?
A.average temperature
B.average precipitation
C.the number of microclimates
D.both temperature and precipitation
7.How is microclimate different from climate?
A.Microclimate is the climate of a small specific place.
B.Microclimate is the climate that affects microbes.
C.Microclimate is the short-term pattern of weather conditions.
D.Microclimate is the climate during a particular season.
8.What do temperature, sunlight, water, and wind have in common?
A.They are all biotic factors.
B.They determine an area's climate.
C.They make up the biota of the biosphere.
D.Their long-term variations determine weather.
9.Which climate zone has winter and summer seasons of about equal length?
A.polar climate zone
B.temperate climate zone
C.tropical climate zone
D.subtropical climate zone
10.Why does the polar climate zone have the coldest climate?
A.At the poles, the Sun's rays strike Earth's surface at the most indirect angle.
B.The lack of water at the poles causes land areas to cool.
C.The lack of plant life at the poles causes heat to be lost to the atmosphere.
D.The biota at the poles absorb heat.
11.Why can't trees grow in the tundra?
A.Their roots cannot anchor the tree in the permafrost.
B.Precipitation is limited and permafrost captures most moisture.
C.There is not enough sunlight.
D.The average temperature is too low.
12.In which biome would you expect to find nocturnal animals and plants with deep root systems?

B.tropical rain forest
C.desert
D.taiga
13.Where do most organisms in a tropical rain forest live?
A.on the forest floor
B.underground
C.in the canopy
D.in the shade
14.Why are mountains not considered biomes?
A.They have no specific plant community.
B.They have a plant community but no animal community.
C.No organisms live on mountaintops.
D.Their plant and animal communities change with elevation.
15.Why do ecosystems located in the same biome but in different parts of the world have similar plants and animals?
A.Every biome shares similar characteristics.
B.All organisms have similar needs.
C.A biome is characterized by a certain set of abiotic factors, no matter where it is found on Earth.
D.All ecosystems in the same biome are identical.
