Chapter 3.3

Question 1

What are the distribution of animals affected by?

Answer 1

Abiotic factors

Question 2

What is Climate?

Answer 2

The average weather conditions in a particular region over a period of time

Question 3

What is climate determined by?

Answer 3

Temperature and rainfall

Question 4

What does the unequal heating of earths atmosphere produce?

Answer 4

Global air and water movements that interact with physical features to produce patterns of rainfall
(Trade winds and ocean currents)

Question 5

What does the pattern of precipitation influence?

Answer 5

the type of soil that forms in different regions

Question 6

What two factors determine the types and abundance of plants that survive?

Answer 6

The unequal heating of the atmosphere and the pattern precipitation

Question 7

what do photosynthetic organisms determine?

Answer 7

The variety and population sizes of animals, fungi, and non-photosynthetic species

Question 8

What are biomes?

Answer 8

Very large ecological areas on the earth’s surface

Question 9

What do biomes include?

Answer 9

A particular mix of plants and animals and other organisms that are adapted to living in a particular environment

Question 10

When does terrestrial life increase?

Answer 10

When temperature and the amount of precipitation increase

Question 11

What is within a biome?

Answer 11

Different habitats

Question 12

What is a habitat?

Answer 12

A place or area with a particular set of characteristics, both biotic or abiotic

Question 13

What is the Range of a population or species?

Answer 13

The geographical area where the population or species is found

Question 14

What is the limit of species range determined by?

Answer 14

Its habitat requirements

Question 15

Why is it possible for species to share the same range or habitat?

Answer 15

Because of their ecological niche

Question 16

What is an ecological niche?

Answer 16

The role that a species members play in a community and its total range of biotic and abiotic requirements

Question 17

What is controlled by limiting factors?

Answer 17

The growth, survival, and distribution of populations

Question 18

What are Limiting Factors?

Answer 18

Abiotic and biotic conditions that limit the number of individuals in a population

Question 19

How are populations controlled by abiotic factors?

Answer 19

Population can be controlled by things like soil, moisture, humidity, etc.

Question 20

What are the 3 biotic limiting factors?

Answer 20

Competition
Predators
Parasites

Question 21

How does competition limit populations?

Answer 21

This happens when the availability for nutrients is limited and individuals must compete for them. This causes the number of births and deaths to decrease

Question 22

What is intraspecific competition?

Answer 22

When members of the same population compete with each other for a limited resource

Question 23

What is predation?

Answer 23

A biotic interaction that involves the consumption of one organism by another

Question 24

What is parasitism?

Answer 24

An interaction in which one organism (The prey) derives its nourishment from another organism (The host)

Question 25

What is the most common way for scientists to estimate the size of a population?

Answer 25

By taking samples and calculating the average

Question 26

How do scientists use Transects to estimate population?

Answer 26

A very long rectangle with a starting point and random direction are chosen. The occurrence of any individual is marked

Question 27

What do ecologists like to use Quadrats for?

Answer 27

For finding the population of organisms that tend to stay in one spot all their lives

Question 28

How do Quadrats work?

Answer 28

Several locations that are the same size are randomly chosen. then the number of species is counted. The density is found by calculating the average number and dividing by the size of the quadrat

Question 29

How can organisms be sampled?

Answer 29

Using transects or quadrats
