Energy and Life
An organism that synthesizes carbohydrates from carbon dioxide and water in the presence of sunlight?
What is a producer (photoautotroph; photosynthetic organism)
A consumer that only eats animals.
What is a carnivore?
The largest trophic level that provides the base of the ecosystem
What is the producer trophic level?
The type of toxins that may undergo biomagnification
What are persistent, fat-souble toxins (persistent means the toxins are not easily broken down)
Certain molecules such as carbon dioxide and methane can trap heat in the atmosphere and called this type of gas
What is a greenhouse gas
The source of energy for most food chains on Earth.
What is the sun?
A consumer that only eats plants.
What is a herbivore?
Fate of most energy acquired by an organisms
What is dissipated as heat
Pregnant women should watch their consumption of these fish
What are shark, swordfish, and certain types of tuna
This process removes carbon dioxide from the atmosphere
What is photosynthesis
The process plants use to create food using from the energy of the Sun.
What is photosynthesis
This is the trophic level of an organism that eats another organism, that eats another organism who ate a producer.
What is a tertiary consumer?
The typical percentage of energy that is transferred from one trophic level to the next in a food chain or ecological pyramid
What is 10%
Fish such as shark, swordfish, and certain types of tuna have high concentrations of this persistent, fat-soluble toxin
What is methyl mercury
Deforestation (the large-scale removal of trees) has this impact on the carbon cycle
What is less photosynthesis to remove carbon dioxide
Bacteria that use energy from inorganic chemicals and fix carbon dioxide in total darkness
What are chemoautotrophs
Organisms that eat other organisms
What are consumers?
The most efficient use of a starch grain (food for livestock or food for humans)
What is food for humans (that are primary consumers)
Saxitoxins produced by some dinoflagellates can cause this.
What is paralytic shellfish poisoning
Mining and combustion of these can lead to more carbon dioxide in the atmosphere
What are fossil fuels
Organisms that create their own food are called producers. They have another name that literally means "self-feeder".
What is an autotroph
A consumer that can eat both plants and animals.
What is an omnivore?
It is the mass of all organsims (of a certain type) in an ecosystem
What is biomass
Domoic acid produced by some diatoms may cause this.
What is amnesic shellfish poisoning
These are 3 common types of fossil fuels
What are coal, petroleum (crude oil), and natural gas (methane)
