What is Deforestation ?
It involves the removal of trees for various purposes such as agriculture, logging and urbanization
_______is a biogeochemical process where oxygen moves through the atmosphere
Oxygen Cycle
What is the hydrosphere ?
This is the part of the earth that contains water
When animals eat other plants/animals ___________________ is transferred
Energy is transferred
How does carbon enter the geosphere ?
Carbon enters the geosphere the process of decomposition and formation of fossil fuel
Koalas mainly eat eucalyptus leaves.They have been declared endangered in parts of Australia.What would be the expected outcome if they become extinct from those ecosystem ?
Increase in eucalyptus leaves.
What organism releases oxygen into the air ?

The sphere includes the continents, the ocean floor , all the rocks on the surface, and all of the sand in the deserts.
Geosphere
Which of the following has more energy in a food chain?
A. Plants
B.Animals
Plants
What is cellular respiration ?
The process in which plants breakdown food and release carbon dioxide into the atmosphere.
What is primary succession ?
the initial colonization and development of an ecosystem on a newly formed or previously barren habitat, like volcanic rock or exposed glacial deposits, where no soil or previous life exists
How does oxygen enter the biosphere ?
It was was very hot and had volcanos releasing different gases such as nitrogen, carbon dioxide, methane into the atmosphere .
It enters the biosphere through the process of photosynthesis.
The sphere that includes all living things ?
Biosphere
How does animal obtain glucose in an ecosystem ?
They obtain glucose by eating plants
How does the concentration of carbon dioxide in the atmosphere affect climate?
As carbon dioxide levels increases, temperature increases.
Wolves are top of the food chain. In the 1970s wolves all but disappeared from Yellowstone. Which of the following was a likely effect of the wolves' dissappearance ?
The biodiversity of plants increased
How did earth first look without oxygen ?
It was was very hot and had volcanos releasing different gases such as nitrogen, carbon dioxide, methane into the atmosphere .
Which of the following accurately describes the movement of carbon between the atmosphere and the biosphere?
Plants absorbing carbon dioxide from the air.
A detailed system of linked food chains in an ecosystem that illustrates the feeding relationships among organisms.
Food Web
How deforestation affects the carbon cycle ?
The removal of trees will lead to more carbon dioxide in the atmosphere because trees absorb carbon dioxide from the atmosphere.
Introduction of a non-native species to a habitat can have adverse effects on the biodiversity of that habitat due to which of the following?
The non-native species competes for resources with native species
What is cyanobacteria ?
The first organism that produced oxygen ?
In what ways is carbon exchanged between the atmosphere and the biosphere?
Photosynthesis and cellular respiration cycle carbon, moving it through the ecosystem. Carbohydrates are produced during photosynthesis. Carbon is released by cellular respiration back into the atmosphere as carbon dioxide.
