Group Behavior
Why do fish form large schools?
To confuse predators and increase survival rates
Why might a population of rabbits decrease if there are more wolves in the area?
More rabbits are eaten by predators (wolves)
Why did elephants start producing tuskless offspring?
Natural selection due to poaching
How do plants get their energy?
Photosynthesis
What do plants need for photosynthesis?
Carbon dioxide, water, light
Why might a pride of lions share food instead of each one hunting alone?
To conserve energy and get more food
What do we call something in the environment (ex. food, space, water) that reduces populations sizes?
Limiting factors
Why did the peppered moth adapt to change colors?
To camouflage to the changing environment to increase survival rates
Why does energy decrease at each step of a food chain?
Organisms use energy for life activities (growth, waste, maintaining body temp, etc)
Why is nitrogen important for living things?
Needed to build proteins
Why might animals work together to raise young that aren't their own?
To increase chances of survival and to pass down genetics
Why might removing the top predator cause prey populations to grow too quickly?
There is nothing controlling the prey (leads to overpopulation)
Why could the resurrection plant survive long periods without water?
Adaptation to survive drought by storing water
Why are top predators fewer in number than plants or herbivores?
Little energy reaches the highest point
What is the importance of a keystone species in the environment?
They maintain balance (homeostasis) and increase biodiversity
Why might a group of bison surround a predator instead of running away?
To defend themselves
Why would elephants make low rumbling noises that humans cannot hear?
To communicate over long distances
Why might sea urchins hide under rocks or in crevices?
Why does matter (such as Nitrogen) cycle but energy does not?
Energy is used up (once it's gone, it's gone), but matter can be reused and recycled
Why does energy flow in a singular direction while nutrients cycle in a food web?
Energy is lost such as heat but matter is reused by organisms
