Ecosystem diversity is

• All the different biomes and the variation within those biomes

• The different temperatures across the globe

• The different countries

• The difference between marine and terrestrial biomes

Percentage cover

• Measure of how many organisms present in an area

• Measure of how much space the species occupies within a given area

• Measure of the number of times a species is present within a given number of samples

• Measure of how frequent an animal is seen

An Ecosystem is

• All the non-living organisms surroundings with which they interact

• All the living organisms and surroundings with which they interact

• All the living organisms and non-living surroundings with which they interact

Biodiversity

• Different races

• The range of living organisms and their environment

• The range of animals in an environment

Ecology is

• Ecology is a branch of biology that studies the interactions among animals and their affecting environment, which includes both biotic and abiotic components

• Ecology is a branch of biology that studies the interactions among organisms and their affecting environment, which includes both biotic and abiotic components

Commensalism is

• when one species benefits from the interaction and the other is neither harmed nor benefits

• when one species benefits from the interaction and another is harmed

• when two different species both gain benefits from the interaction

• when one species is the predator and the other the prey

Species diversity

• The number of plants in a habitat

• The number of humans in an area

• The number of different species in a habitat

• The number of animals in a habitat

A symbiotic relationship is

• Different species living together for an extended time

• when one species benefits from the interaction and another is harmed

• when two different species both gain benefits from the interaction

• when one species is the predator and the other the prey

Tolerance range

• Range of pain a species can endure

• Range of conditions in which a species are able to survive

• Range of temperatures that a species can survive

• Range of pH that a species can survive
