Food Chains and Food Webs
This type of organism makes its own food using sunlight.
What is a producer?
In this relationship, one species benefits while the other is neither helped nor harmed.
What is Commensalism?
Plants take in this gas during photosynthesis.
What is carbon dioxide?
This process converts nitrogen gas from the air into a form usable by plants.
What is nitrogen fixation?
This gas is the main contributor to the greenhouse effect.
What is Carbon Dioxide?
A diagram showing a direct line of how energy moves from one organism to another in an ecosystem is called this.
What is a food chain?
In this type of symbiosis, both species benefit.
What is mutualism?
This process by animals and plants releases carbon dioxide back into the atmosphere.
What is respiration?
Bacteria in the soil convert ammonium into nitrites and nitrates through this process.
What is nitrification?
Name given to gases, like methane and nitrous oxide, that trap heat in Earth’s atmosphere.
What are greenhouse gases?
In a food web, these 2 types of organisms break down dead material and return nutrients to the soil.
What are Fungi and Bacteria?
This worm attaches to the intestines of mammals, obtaining nutrients at the host’s expense.
What is parasitism?
Carbon stored in these 3 underground deposits.
What is Coal, oil and natural gas
When plants and animals die, decomposers release nitrogen back into the soil in this form.
What is ammonium?
This human activity is the largest contributor to increased greenhouse gases.
What is burning fossil fuels?
Energy is passed on from one organism to the next in an ecosystem. Energy is lost through this way
What is heat energy?
In this relationship, fungi provide minerals to algae, while algae supply carbohydrates to fungi.
What is mutualism?
This process occurs when excess carbon dioxide from the atmosphere dissolves in seawater, forming carbonic acid and lowering the pH.
What is Ocean Acidification?
This gas makes up the highest percentage of the air and is needed by plants.
What is nitrogen?
Melting ice caps and rising sea levels are examples of this global effect.
What is Climate Change?
If a top predator is removed from a food web, this effect occurs through the ecosystem.
What is a trophic cascade?
The name given to the relationship between golden jackal which will follow a tiger to eat the leftover scraps from the tiger's kills.
What is commensalism?
Long-term carbon storage occurs when dead organic matter is compressed over millions of years to form these fuels.
What are fossil fuels?
When fertilizers or waste add too much nitrogen to soil or water, it can cause this problem in ecosystems.
What is eutrophication?
This process involves removing CO₂ from the atmosphere by forests, soil, or oceans, and is a critical strategy for mitigating climate change.
What is carbon sequestration?
