Where does photosynthesis take place?
In the chloroplasts

Name the producer in this food web
Grass

What is the difference between a food web and food chain?
Food webs are linear/more simplistic. Food webs have multiple organisms in each trophic level
100
What is carrying capacity?
Largest number of organisms an ecosystem can support for a long period of time

Use the image to answer the question. Why does the hare population plummet after the Lynx population spikes?
Too many predators, they will consume all prey
200
What chemical reaction does this equation represent? C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
Cellular respiration

What would happen to the hawk population if the kit fox population skyrocketed?
Hawk population would deplete, kit foxes would eat more ground squirrels leaving less food for hawks.

How do invasive species harm their new environment?
outcompetes native species.

What is a symbiotic relationship?
An interspecies relationship (between two different organisms) where at least one organism benefits.

What is the difference between autotrophs and heterotrophs? Give an example of each
Auto makes their own food, hetero needs to consume other organisms for food! Mx. Hunt judges exmaples

What are the tertiary consumers in this food web?
hawk/ rattlesnake

List 3 limiting factors in an ecosystem
potential answers
food water shelter competition predators space

Why does the Lynx population plummet after the hare population does?
No food! The population of Lynx can not sustain itself

List the SECONDARY Consumers of this food web
Snakes

What would happen to the population of scorpions if there was plentiful water and sunlight for the plant population to succeed? Why?
Scorpion population should go up. Good conditions should make more food for grasshoppers, therefore increase their population. Then there would be more food for scorpions!

What is one way humans harm the environment?
deforestation, climate change, overexploitation

Name the chemical compounds that are required for photosynthesis to occur, and the chemical compounds required for cellular respiration to occur. How are they related?
PS: Carbon dioxide, Water, Sunlight
CR: Glucose Oxygen
CR uses PS products vice versa
500
Why is energy lost between trophic levels?
Energy is used for bodily functions like digestion, walking, etc.

What purpose does the bacteria serve in this food web? What kind of organism is it?
Break down dead things / Decomposer
500
Why is genetic diversity important?
Protection from natural disasters, more nutrients and different kinds of food for humans
