Which is an example of genetic biodiversity?
Different skin color within a species
Different types of species within an ecosystem
Every organism has the same genetic sequence
All populations look the same within a species
Which of the following situations contributes to stability in an ecosystem?
increase in biodiversity
decrease in biodiversity
extinction of a population from the ecosystem
removal of many populations of organisms
What are three things that create biodiversity?
species, genetic variation, and ecosystem
mutation, disorder, regression
genes, cells, traits
water, land, mountains
The ocean ecosystem has a high sustainability because of
strong, persistent currents
predator/prey relationships
green plants growing on the bottom
the large variety of different organisms
1. The ecosystem with the greatest sustainability will be the one that has the –
greatest variety of different organisms
highest annual precipitation
lowest population of harmful insects
fastest growing season of green plants
Why does biodiversity contribute to a habitat’s sustainability?
The more plants and animals in a habitat, the greater the biomass, which is how habitats store energy.
The greater the number of species, the more competition there is for food between predators, which sustains their populations.
Changing conditions that harm one species leave other species to survive and perhaps even thrive.
Landforms change shape less frequently when there is a greater number of species using the land.
