Ecology Flashcards
If a trait has helped a species survive will it be passed on to the offspring? Yes or No?
Yes
These helpful traits like beak shapes, speed, and long necks are called?
Adaptations
Natural Selection is a concept that who developed?
Charles Darwin
Natural Selection says that: organisms that are best ___ will most likely survive, those that survive will likely ___, helpful genetic ___ will be passed on to the offspring. More offspring are produced than can ___ , all organisms ___ , for needed resources
Adapted,
If there are 7 species of fish living in the same pond, then competition for resources will be high. If one species adapted to feed at night, this helps reduce the competition by giving this species a new role or __________________ in the habitat.
Niche
A shark is a predator in the ocean. What adaptations do sharks have that allow them to be good predators?
Fins to swim better, Eyeslids so sharks can see under water
Sally loves to grow tomatoes every summer in her greenhouse. Last year she had a horrible infestation of tomato hornworms ruining her crop. She applied a pesticide and saw immediate results. Thankfully almost all of the caterpillars died and her tomato crop was saved. This year the hornworms returned but when she applied the pesticide she did not have the same results. Why do you think this was so?
If a predator population increases, what happens to the prey populations? Increase or decrease
If two species have a mutualistic relationship, then they live better together. This means that their populations will… both increase or both decrease or one increases and one decreases or nothing
What are the 4 things organisms compete for?
What type of relationship to the Phytoplankton and Cod have?
Name a relationship in the food web that would be predator-prey.
The jackrabbit provides energy for what organisms?
Name the producer-consumer relationships you see below? (HINT: There is more than one!)
