Wildfire

Question 4

These biotic factors control the population of prey in an ecosystem

Answer 4

predators

Question 5

Remember

Answer 5

DNA Replication

Question 6

Remember

Answer 6

Gestation Period

Question 7

“virulently poisoned breath of an ox” and its excretions and hide are examples of this process

Answer 7

Disease transmission

Question 8

The delivery of this process was sped up when someone “dressed as a local, with mutton fat rubbed in his hair, could walk among them and stick in a needle and barely be noticed”

Answer 8

Rinderpest Vaccination

Question 9

Buffaloes and wildebeests are examples of these organisms that fall victim to predators

Answer 9

Prey

Question 10

These organisms are not picky eaters—grizzlies and humans are examples of these (lucky you, you’re both!)

Answer 10

Omnivores

Question 11

This type of relationship could be described as intraspecific or interspecific

Answer 11

Competition

Question 12

Penalties for these wildlife crimes in Kenya include life imprisonment in some cases—the illegal trafficking and killing of wildlife

Answer 12

poaching

Question 12

Camera trap data, a video recording, and a narrative provided evidence for this type of variety in an ecosystem

Answer 12

High biodiversity

Question 13

These species are considered to have a massive impact on their ecosystem; without them, an ecosystem collapse is imminent

Answer 13

keystone species

Question 14

90% of energy transferred between trophic levels is lost as this

Answer 14

heat

Question 15

These two conservation laws are observed in all biological processes

Answer 15

Law of Conservation of Matter and Energy?

Question 15

The energy conversion that occurs when a consumer leaps to safety after eating a meal

Answer 15

chemical energy to heat/motion energy?

Question 16

This nonliving thing confuses humans because it contains genetic material AND it can replicate (but only with a host)

Answer 16

Viriuis

Question 17

What is carrying capacity?

Answer 17

species’ average population size in a particular habitat

Question 17

This is an environmental factor that has the capacity to restrict the growth, abundance, or distribution of a population in an ecosystem

Answer 17

Limiting Factor

Question 17

Arrange the following biological hierarchies in order of smallest to largest:
Ecosystem
Population
Community

Answer 17

population, community, and ecosystem

Question 18

Explain the ecosystem balance brought upon by the relationship between hot fires and wildebeests.

Answer 18

More wildebeests = less tall grass = less hot fires, less hot fires mean stability in the ecosystem

Question 19

What happens when populations exceed carrying capacity

Answer 19

Ecosystem becomes unsuitable for species to survive

Question 19

Density dependent vs. density independent factors

Answer 19

Density-independent factors are not influenced by a species population size.

Density-dependent factors have varying impacts according to population size

Question 20

What happens as population sizes increase

Answer 20

resources become less

Question 21

What is biodiversity?

Answer 21

the variety of all living things and their interactions

Question 22

3 different biodiversities

Answer 22

genetic diversity, species diversity and ecosystem diversity

Question 22

What is a keystone species?

Answer 22

an organism that helps hold the system together

Question 22

Why is biodiversity important?

Answer 22

All living life depends on it

Question 23

Example of keystone species

Answer 23

Saguaro Cactus

Question 24

What is species richness?

Answer 24

Species richness is simply a count of species

Question 24

What is an invasive species

Answer 24

An invasive or alien species is an introduced species to an environment that becomes overpopulated and harms its new environment

Question 25

Increased CO2 is doing to our planet?

Answer 25

warming the planet

Question 26

What does deforestation do to the carbon cycle?

Answer 26

much of the carbon stored by trees is released back into the atmosphere as carbon dioxide, which contributes to climate change.

Question 26

What are we doing that is increasing CO2 levels

Answer 26

burning of fossil fuels like coal and oil

Question 27

Movement of energy through an ecosystem

Answer 27

Energy is transferred between organisms in food webs from producers to consumers

Question 27

What is ATP? How does ATP work

Answer 27

Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level.

Question 27

Know the four spheres (atmosphere, hydrosphere, biosphere, geosphere) and how carbon can move through and between them.

Answer 27

Carbon cycles through the atmosphere, biosphere, geosphere, and hydrosphere via processes that include photosynthesis, fire, the burning of fossil fuels, weathering, and volcanism

Question 28

What are the three macromolecules that provide us energy?

Answer 28

Carbohydrates, proteins, and fats

Question 28

Enzymes are what type of macromolecule? What do they do?

Answer 28

protein macromolecules. Proteins are large biopolymer molecules that are made up of repeating monomer units called amino acids. There are 20 different common amino acids that make up proteins like enzymes. Of these, nine amino acids are essential, which means you must get them from your diet.
