Q

Explain how the natural sciences and social sciences interact in environmental sciences?

A

Cultural services control how a living species reacts to their environment, it affects disease, water, and how a species pollutes the environment around them. This affects the environmental science in an area.

Q

Why do all pyramids, numbers, energy, and biomass look the same?

A

With plants you can support herbivores which can support carnivores which eat large amounts of each other

23
Q

What is the 90 10 rule

A

90% of energy is lost at every tropic level to heat and waste, only 10% becomes biomass

24
Q

Why is eating lower on the food chain means more food for all humans?

A

Eating vegetarian makes 10x as much plant energy available for other humans

25
What is gross primary productivity
Total amount of solar energy captured (Co2 incorporated into C6H1206)
26
What is net primary productivity
Gross productivity - respiration
27
What are the predator and prey benefits from acquiring food
Prey benefits from “culling of the heard” aka weakest of the population die off pushing evolution of the group to make it more fit.
28
What is intraspecies competition?
Between members of the same species
29
What is interspecies competition?
Between members of different species
30
What is symbiosis?
A close, long term relationship between two species in which at least one species benefits
31
What are Ectoparasites?
Things that live on the host surface
32
What are endoparasites?
Live inside the body of a host
33
What is commensalism
One organism benefits while the other is not affected.
34
What is mutualism?
Both species benefit The relationship is often obligatory, as neither can exist without the other
35
What is an indicator species?
Low tolerance for habitat change
36
What is a keystone species
Has a niche that affects other animals in the ecosystem
37
What happens when water goes into ground from rain?
It infiltrates into the ground and collects as groundwater in aquifers
38
What is water that evaporates from plants?
Transpiration
39
What is water that comes from ice?
Sublimation
40
What is when nitrogen fixing soil in bacteria is converted to ammonium?
Ammonification
41
What is when nitrifying bacteria’s convert ammonium to nitrates
Nitrification
42
Decomposes turn into this in the nitrogen cycle
Ammonium
43
What is when nitrates are used by plants?
Assimilation
44
What is respiration
When a consumer releases carbon into the atmosphere
45
What is combustion?
When fire or volcanic sources release stuff into atmosphere
46
What do fossil fuels lead to?
Extraction
47
Decomposers and fires result in blank which makes fossil fuels
Burial
48
In the ocean dissolved phosphates become
Phosphate rocks
49
Dissolved phosphates are consumed by
Producers
50
When a human uses phosphate mining in their house it is
Detergents
51
Fertilizers and humans do this to phosphates in soil
Leaching
52
What are three ways humans are increasing the CO2 in the biosphere?
1. Burning fossil fuels atmospheric CO2 and global climate change 2. Cutting down trees and burning rainforest adds Co2 to the atmosphere 3. Making cement released Co2 from the (chemical formula i can’t read) converted into limestone
53
What is the primary negative effect of having too much phosphorus in bodies of water?
Fertilizer and detergent get into bodies of water where p along with n is the limiting nutrient for algae growth. Trigger eutrophication.
