Intro to ecology
What is the missing from the food chain
Caterpillar------- small Bird---------crocodile
The producer/Plant
What does the arrows represent in a food chain?
A- Energy Flow
B-What is being eaten
A- Energy Flow
What is the misconception about photosynthesis?
A-Photosynthesis requires light to make carbon dioxide
B- Respiration breaks down glucose to make energy
B- Respiration breaks down glucose to make energy
These are proteins that break down food. They can be found in the saliva, stomach and small intestines.
Enzymes
During the winter they add salts to the road to melt the ice. What would you expect to happen to the nearby plants on the side of the road?
A-Plants would absorb water and spring new buds
B-Plants would wilt and die faster
B-Plants would wilt and die faster
If the deer population in a forest grew exponentially to 200 then became stagnant over 6 months. What could be happening to the deer population?
A- A predator has been introduced into the forest.
B- The forest ecosystem has reached the carrying capacity for the deer
B- The forest ecosystem has reached the carrying capacity for the deer- the maximum number of individuals of one species that the environment can support
If an ecosystem has 50,000J to 90 animals. How much energy would be left for the Secondary consumers?
500J
The teacher made a mistake in the statement below. Fix the statement to make it correct/explain the error.
Plants do not carry out respiration because they get their energy from the sun.
Plants do carry out respiration because they still need to break down the food (glucose) they make from photosynthesis
Plants carry out respiration and photosynthesis even though they produce their own food from the sun.
Name the macromolecule that provides long term energy.
Fats/lipids
The smooth endoplasmic reticulum makes fats and gets rid of toxins in the body. John drinks alot of alcohol and needs to get rid of the toxins. How would the ER be different in his cells?
A- He would have a lot of folds in his ER to process all those Toxins
B-He would have less ER because the Toxins would destroy they ER
A- He would have a lot of folds in his ER to process all those Toxins
