Chapter 52 & 56 (Ecology)

Question 1

Ecology

Answer 1

is the scientific study of the interactions between
organisms and the living and nonliving components of their environment. These interactions determine the distribution of organisms and their abundance

Question 2

Abiotic Factors

Answer 2

including nonliving attributes such as

temperature, light, water, and nutrients

Question 3

Biotic Factors

Answer 3

including other organisms that are part of an individual’s environment

Question 4

Habitat

Answer 4

place where an organisms lives and reproduces

Question 5

Organismal ecology

Answer 5

it studies how an organism’s structure, physiology, and (for animals) behavior meet environmental challenges. Includes physiological, evolutionary, and behavioral
ecology

Question 6

Population

Answer 6

is a group of individuals of the same species living in an area

Question 7

Population Ecology

Answer 7

focuses on factors affecting population size over time

Question 8

Community

Answer 8

a group of populations of different species in an area

Question 9

Community ecology

Answer 9

examines the effect of interspecific interactions on community structure and organization

Question 10

Ecosystem

Answer 10

the community of organisms in an area and the physical

factors with which they interact

Question 11

Ecosystem ecology

Answer 11

emphasizes energy flow and chemical cycling between organisms and the environment

Question 12

Landscape

Answer 12

is a mosaic of connected ecosystems

Question 13

Landscape Ecology

Answer 13

focuses on the exchanges of energy, materials, and organisms across multiple ecosystems

Question 14

Biosphere

Answer 14

is the global ecosystem, the sum of all the planet’s ecosystems and landscapes

Question 15

Global Ecology

Answer 15

examines the influence of energy and materials on organisms across the biosphere

Question 16

Ecosystem

Answer 16

consists of all the organisms living in matter an area, as well as the abiotic factors with which they interact

Question 17

Biomes

Answer 17

are major life zones characterized by vegetation type

terrestrial biomes) or physical environment (aquatic biomes

Question 18

Disturbance

Answer 18

is an event such as a storm, fire, or human activity

that changes a community

Question 19

Biodiversity

Answer 19

Is the total number of species, the variability of their genes, and the communities in which they live. Biodiversity has three main components: Genetic, Species and ecosystem diversity

Question 20

Ecosystem Diversity

Answer 20

Variety of species in a particular space,

dependent on the species interactions

Question 21

Species diversity

Answer 21

variety of species that make up a

community

Question 22

Genetic diversity

Answer 22

variety among members of population

Question 23

Most species loss can be traced to four major

threats:

Answer 23

–Habitat loss
–Introduced species
–Overharvesting
–Global change
