How do sulfur and phosphorus move from the biotic to the abiotic pools during their cycles

Decomposers break down the remains of producers and consumers

Clouds dump around 100 billion gallons of water on rainforests each year. How much rain is evaporated from the rivers, lakes and surface of rainforests each year?

around 100 billion gallons

The process of photosynthesis is essential in the oxygen/carbon dioxide cycle. Photosynthesis removes ______ from the atmosphere and produces and releases ______ into the atmosphere.

carbon dioxide, oxygen

The relationship between humans and their digestive bacteria can be described as

mutualism

ecology

the branch of biology that deals with the relations of organisms to one another and to their physical surroundings.

The ocean's biological carbon pump is driven by organisms that live in there. Just like the terrestrial carbon cycle, the oceanic biological carbon pump is all about photosynthesizing, respiring, eating, producing waste products, dying and decomposing. The biological pump plays a major role in all BUT ONE of the processes involved in oceanic carbon cycling

upwelling currents bringing deep, cold ocean water to the surface to warm and release carbon back to the atmosphere

Carbon is a major component of all organic compounds, including carbohydrates, lipids, proteins, and nucleic acids. Carbon dioxide is continually exchanged between the atmosphere and oceans. What geological process returns carbon to the atmosphere in the form of carbon dioxide?

volcanic activity

Most successful parasites, such as this cat flea, weaken their host but do not kill it. Why is killing its host usually disadvantageous for a parasite?

If a parasite kills its host, it will then have to find a new host in order to survive.

__________ species reproduce rapidly in a new habitat due to the lack of parasites and predators that would naturally control their population growth.

Invasive

How is the sun the major source of energy in the water cycle?

It provides the energy to evaporate water on Earth into the atmosphere

The red-cockaded woodpecker is found in the pine forests of Georgia. It eats insects found in the barks of the pine trees and nests in the trees. How will a reduction in the number of pine trees MOST LIKELY affect the red-cockaded woodpecker.

It will decrease in number

Humans shift carbon to the atmosphere in many ways. And because of the law of conservation of matter, there it stays as the primary greenhouse gas. By extracting fossil fuels, we remove carbon from storage in the lithosphere. By burning those fossil fuels, we move carbon dioxide into the atmosphere. All BUT ONE human activity increases the amount of atmospheric carbon.

planting cover crops

A lion would be considered a ________ of a gazelle

predator

If the population of bobcats in Yellowstone Park increases, it will directly affect the number of

prey in the ecosystem

In any food web, the organisms that are responsible for converting raw energy into usable chemical energy are collectively called ________ while organisms that recycle the nutrients trapped in dead organisms are collectively called

producers; decomposers.
