Ecology

Question 1

Habitat

Answer 1

A place where living organisms live

Question 2

Biotic unit

Answer 2

Living organisms

Question 3

Abiotic unit

Answer 3

Non-living things (temperature range, soil pH, water, nutrient availability, wind rate, humidity)

Question 4

Population

Answer 4

Number of species living in a certain area at the same time

Question 5

Community

Answer 5

Multiple different organisms living in the same place at the same time in an ecosystem

Question 6

Ecosystem

Answer 6

The interactions between the biotic and the abiotic factors make up an ecosystem

Question 7

Niche

Answer 7

Role of an organism in its natural environment; the way in which it interacts and impacts other organisms and abiotic components of environment

Question 8

Biome

Answer 8

Biotic unit that includes various communities that have a common adaptation to that particular environment

Question 9

Trophic Levels

Answer 9

Producers
Primary Consumers
Secondary Consumers
Tertiary Cnsumers
Apex Consumers
Decomposers - get their energy by feeding on dead and decaying bodies and waste organic materials. Essential in order to break down complex molecules into simple molecules (increases nutrient availability), helping plants grow.

Question 10

Symbiotic Relationships

Answer 10

Symbiotic: Two/more different species living together in which at least one of the species benefits
Predator-prey: how one organism kills another and consumes it as food
Mutualism: When both the species in a relationship benefit from each other
Parasitism: When one organism is benefitted and the other is harmed. Benefitted organism = parasite, harmed organism = host
Ectoparasite: parasites that live outside of the host
Endoparasite: parasites that live inside the body of the host
Commensalism: When one organism benefits and the other is neither benefitted nor harmed

Question 11

Food chain

Answer 11

Sequential flow of energy from one trophic level to another

Question 12

Ecological value

Answer 12

the level of benefits that the space has. Eg: water, materials, biota

Question 13

Biota

Answer 13

Plant and animal life of a particular region or period

Question 14

Cascade effect

Answer 14

when one trophic level is affected, other trophic levels will be affected as well

Question 15

Ocean acidification

Answer 15

reduction of pH of the ocean caused by increased levels of CO2 in the atmosphere

Question 16

Permafrost melting

Answer 16

ice inside the permafrost melts, leaving behind water and soil

Question 17

Food web

Answer 17

multiple food chains linked together/interconnected.
