Pollination
Germination
Homeostasis
Photosynthesis
What is the correct type of energy transfer that takes place during the process of photosynthesis?
Thermal energy to chemical energy.
Chemical energy to light energy.
Light energy to chemical energy.
Chemical energy to chemical energy.
Which is NOT an element found in the process of photosynthesis?
Hydrogen
Nitrogen
Carbon
Oxygen
_____________________ is a product of photosynthesis.
Carbon dioxide
Sunlight
Glucose
Soil
Which of the following is NOT a requirement for photosynthesis to take place?
Soil
Sunlight
Water
Carbon Dioxide
Photosynthesis requires three key factors. If only two of those three factors are present, what is the most likely thing to occur?
Photosynthesis would likely still occur, it would just use those two factors more.
Photosynthesis would still occur, as long as those factors are water and carbon dioxide.
Photosynthesis would not occur.
Photosynthesis will convert into chemosynthesis.
In an energy pyramid / food chain, a primary consumer would most likely be considered a ____________________.
herbivore
ominovre
carnivore
decomposer
Which choice below shows the correct order of a food chain?
Herbivore --> producer --> omnivore --> decomposer
Producer --> herbivore --> carnivore --> decomposer
Producer --> omnivore --> decomposer --> carnivore
Decomposer --> carnivore --> herbivore --> producer
A population of salamanders lived in a small cave. There were many ferns and mosses that grew at the entrance of the cave. One day, a giant rock fell from the roof of the cave and completely blocked the entrance of the cave. What most likely happened to the salamanders in the cave?
The salamanders survived because they could breathe the carbon dioxide that they produced.
The salamanders survived because they have plenty of oxygen from the other animals in the cave.
The salamanders died because they could not get enough oxygen from the plants.
The salamanders died because they could not get enough carbon dioxide from the plants.
Which of the following is not correct about plant cells found in plant leaves?
They consume other organisms for food.
They make sugar in the form of glucose.
They absorb sunlight for energy.
They take in carbon dioxide.
In an energy pyramid, which organism would have the least amount of energy from the Sun?
A blueberry bush
A rabbit
A grizzly bear
A bald eagle
Based on the food web, the populations of which two organisms would directly impact the population of grasshoppers?
Carrots and owls
Birds and grasses
Mice and grains
Foxes and mice
Which of the following correctly shows a flow of energy through the food web?
Grasshopper --> sparrow --> hawk
Snake --> toad --> grasshopper
Sparrow --> hawk --> rabbit
Rabbit --> hawk --> grass
Where is 100% of the energy that is formed in a swamp?
In producers, such as algae.
In herbivores, such as deer.
In carnivores, such as an alligator.
In decomposers, such as bacteria.
The starting source of energy for all of the organisms in a food pyramid is —
water
sunlight
oxygen
carbon dioxide
As energy moves up an energy pyramid, it ______________________.
increases
decreases
decreases, then increases
increases, then decreases
Which is the most likely scenario to happen if the top predator in an ecosystem is eliminated from it?
decomposers will adjust to become the top predator
animals that are normally prey would overpopulate and over eat
herbivores would evolve and become carnivores
herbivores would reproduce more and eat less producers.
The Sea Otter is a keystone species in its food web. It feeds on abalone, urchins, and mussels. Those three organisms feed on the kelp in the ecosystem. Why would the food web fall out of balance if the Sea Otters were no longer in the ecosystem?
The kelp would over grow.
There would be no real difference.
The three organisms that eat kelp would over eat it until there is no food left in the ecosystem.
The three organisms that eat kelp would eat less of it and the kelp would take over the ecosystem.
Food Webs and food chains never change. They will always be the same.
True
False
Every organisms in an ecosystem plays a role. Keystone species .....
maintain the balance for a healthy ecosystem.
clean up the ecosystem.
are the top predator in an ecosystem.
all go through photosynthesis.
