1.1 ecosystems

Question 1

one organism

Answer 1

individual

Question 2

Group of individuals of the same species

Answer 2

Population

Question 3

all living organisms in an area

Answer 3

Community

Question 4

all living and nonliving things in an area

Answer 4

Eco system

Question 5

large area with similar climate conditions that determine plant and animal species there (e.g. tropical rainforest)

Answer 5

biome

Question 6

organisms fighting over a resource like food or shelter; limits population size

Answer 6

Competition

Question 7

One organism using another for energy source

Answer 7

Predation

Question 8

Relationship that benefits both organisms (coral reef)

Answer 8

Mutualism

Question 9

relationship that benefits one organism and doesn’t impact the other (birds nest in trees)

Answer 9

Commensalism

Question 10

(plant eaters) eat plants for energy (giraffe and tree)

Answer 10

Herbivores

Question 11

(carnivores) kill and eat pray for energy (Leopard and Giraffe)

Answer 11

True predators

Question 12

use a host organism for energy, often without killing the host and often living inside the house (e.g. Mosquitoes, sea lamprey)

Answer 12

Parasites

Question 13

lay eggs inside a host organism; eggs hatch and larvae eat host for energy (e.g. Parasitic wasps, bot fly)

Answer 13

Parasitoids

Question 14

any close and long-term interaction between two organisms of different species

Answer 14

Symbiosis

Question 15

What are examples of symbiotic relationships

Answer 15

mutualism (+/+), commensalism (+/o), parasitism (+/-)

Question 16

reduces population size since there are fewer resources available and fewer organisms can survive

Answer 16

Competition

Question 17

different species using the same resource in different ways to reduce competition

Answer 17

Resource partitioning

Question 18

using resources at different times, such as wolves and coyotes hunting at different times (night vs day)

Answer 18

Temporal partitioning

Question 19

using different areas of a shared habitat

Answer 19

Spatial partitioning

Question 20

using different resources based on different evolved body features

Answer 20

Morphological partitioning
