How does too much fishing in an area affect its ecosystem?
The population of that fish species will decline
Could affect the number of algae
Could affect the top predators
All of the choices would most likely happen
Which of the following is currently a primary cause of species decline worldwide?
habitat destruction
intraspecific competition
Hunting
viral outbreaks
Species that migrate into an ecosystem or are deliberately or accidentally introduced into an ecosystem by humans and whose presence crowds out populations of native species, cause human health problems, and lead to economic losses.
invasive species
endangered species
introduced species
threatened (vulnerable) species
An event in which a large percentage of all living species become extinct in a relatively short period of time.
Habitat fragmentation
Mass extinction
Overexploitation
Background extinction
What actions decrease biodiversity?
Pollution
Habitat Destruction / Loss
Monocrop Farming / Mining / Overfishing / Over hunting
All of these are correct
Why is biodiversity so important?
Because all species depend on each other to survive, so if one becomes extinct another species that relies on it could go extinct as well
Because it’s better to have only one variation of each species.
Because it better to only have a few species on Earth.
