Ecosystem Basics
This type of factor in an ecosystem is living.
Biotic factor
In this food chain, this organism is the producer
Sun → Grass → Grasshopper → Frog → Snake → Eagle
Grass
The Arctic fox’s white winter fur is an example of this type of survival feature.
Adaptation
Destroying wetlands can increase this problem during heavy rainfall
Flooding
This type of organism carries out photosynthesis to make its own food.
Plant
Rocks, sunlight and water are examples of this type of ecosystem factor.
Abiotic factors.
In the following food chain, if the frog population decreased, this population would increase the most
Sun → Grass → Grasshopper → Frog → Snake → Eagle
Grasshopper
Camels have thick eyelashes to protect them from
Flying sand in the desert
Cutting down forests can destroy the places where organisms live. Places where organisms live are called
Ecosystems or habitats
Organisms need sunlight, water, and this gas from the air to perform photosynthesis.
Carbon dioxide
In a pond, algae and insects would be classified as this.
Biotic factors.
In the following food chain, if the frog population decreased, what would happen to the eagle population?
Sun → Grass → Grasshopper → Frog → Snake → Eagle
The eagle population would decrease
An duck living in a wetland would have webbed feet because
Webbed feet help the duck swim in water
A species brought into a new environment that harms a native species is called
An invasive species
This gas is released into the atmosphere during photosynthesis.
Oxygen
Photosynthesis
This kind of organism breaks down dead material and returns the nutrients to the soil.
Decomposer/detritivore
This ecosystem has very low rainfall and can be very hot or cold
Desert
When pollution enters a lake and kills many fish species, this is most likely reduced in the ecosystem.
Biodiversity
The main product of photosynthesis is:
Glucose (energy)
Without producers (plants) in an ecosystem, these organisms would eventually decrease because there would be no energy source?
Consumers
All energy in food chains originally comes from this source
The Sun
Equator
Why is biodiversity important in ecosystems?
The more biodiverse an ecosystem is, the more resilient it will be.
What is the point of photosynthesis.
It allows plants to generate energy without having to eat anything.
