100

This is the ultimate source of energy for life on earth

The Sun (sunlight)
100

These organisms produce energy through the use of photosynthesis

What are autotrophs/producers

100

What is the molecule carbon is part of in both the processes of cellular respiration and photosynthesis?

What is carbon dioxide/ CO2?

100

What do arrows represent in a food web?

 The flow/transfer of energy

200

A series of events in which one organism eats another and obtains energy. Usually written on one line.

What is a food chain?

200

These organisms are herbivores, therefore they are called ______________ consumers.

What is primary?

200

What single celled organisms "fix" Nitrogen in soil for use in plants and other organisms?

What is bacteria?

200

Why is it more energy efficient to have a vegan diet instead of a carnivore diet

there is more energy at the producer trophic level on the energy pyraimid

300

Matter is not created or destroyed, but rather it is ________ through nature

Recycled

300

These organisms are typically at the top of the food chain. They are called ____________ consumers.

What is tertiary?

300
what types of matter(molecules atoms) are gained by consumers from producers in the food chain?what type of matter is excreted during cellular respiration from consumers?
when consumers eat producers, they receive matter in the form of glucose from them. They will excrete CO2 as a gas waste when they exhale.
300

A forest fire burns down several trees in a forest. Compared to normal levels, what would happen to the amount of CO2, O2 , and the biomass of the area if it was measured a few days later?

The amount of CO2  would be higher


The amount of O2 would be lower


The biomass of organisms in the area would be lower



400

An organism that breaks down wastes and dead organisms.

What is a decomposer?

400

This is a way to show how energy in a food web is allocated. Usually there is a large base and a pointed top.

What is an energy pyramid?

400

suppose you are studying the population of blue finned tuna(a large fish) in the Atlantic Ocean. Name a biotic limiting factor to consider in your research.

amount of food(small fish/prey), amount of mates(other tuna)

400

suppose the rabbits in a food chain got a disease that caused fatalities, how would that impact the biomass of hawks, snakes, and grass?

grass would increase and the consumers above the rabbit(snake and hawks)would decrease

500

The process of burning off carbon-based products such as gasoline and propane, creating carbon dioxide

Combustion

500

What is the percentage of energy LOST as it moves from producer to primary consumer to secondary consumer?

What is 90%?

500
The carrying capacity of a group of deer is 200 in Connetquot State Park. Suppose the amount of deer temporarily increased to 300 in the short term. what would be the impact on the food chain and the amount of limiting factors in the area before and after this event

when the population increases to 300, the deer will compete with one another for the limiting factors in the area(amount of grass, amount of water, mates).  when the resources are depleted, this can cause the amount of deer to decrease severely below carrying capacity, which could cause the food chain to collapse/fail.

500

If the producer level has 12,000 kCal of energy, how much energy is left over at the tertiary consumer level?

12 kCal of energy
