Which statement below refers only to biotic components in an ecosystem?
Evaporation, transpiration, and precipitation are complex processes that cycle water between the atmosphere and the Earth's surface.
Photosynthesis and respiration are not considered atmospheric processes.
Vegetation is an indicator of several environmental factors, including precipitation, temperature, soil, geology, and wind.
In Yellowstone Park, shrubs have expanded their range into large areas formerly populated by short grasses, due to overgrazing and trampling by livestock.
A student walks the schoolyard and observes that there are many living things such as different plants and animals. She notices that moss grows in moist shady areas but did not see any in the open yard where its sunny. What is the best explanation for her observation?
Different habitats support different plants and animals
All plants and animals can live in any environment
Schoolyards are not able to sustain living things
Schoolyards are the only places where moss can grow.
In the ocean

Increasing biodiversity affects the sustainability of an ecosystem by
always decreasing competition for limited resources within an ecosystem
allowing an ecosystem to survive many changes
preventing an ecosystem from surviving many changes
always increasing competition for limited resources within an ecosystem
Which of the following factors determines a biome's identity
the climate that exists there
the number of people who live there
the amount of pollution that occurs there
the types of activities that can be done there
Which statement is true?
There are a few number of animals that live in the rain forest, and they belong to a small number of species.
The population of animals in the rainforest is large and diverse.
Many animals live in the rainforest, but there are just a few species that can survive there.
There are many species living in the rainforest, but their populations are usually very small.
Anastayjia visited 3 different ecosystems to collect specimens. She visited a grassy area in a tundra and woody area in a Temperate deciduous forest. She collected 20 different types of species from the tundra and 98 different types of species from the forest. Which ecosystem is the MOST sustainable?
Tundra
Desert
Temperate deciduous forest
Rainforest
What is true about sustainability?
Having a small number of species increases biodiversity
Sustainability is how organisms change over time
Sustainability is how much rainfall and sunlight an ecosystem receives
The more different types of species you have (biodiversity) the better an ecosystem can sustain itself
A certain area of the Indian ocean is expected to dry up and become a desert over thousands of years. What will happen to the sustainability of this ocean?
Sustainability would increase because the number of species would increase
Sustainability would remain the same
Sustainability would decrease because the number of species would decrease
Not enough information is given
