How an individual meets the challenges of an environment.

Question 2

WHAT IS POPULATION ECOLOGY?

Answer 2

Answer 3

Studies the interactions between species being: Predation, competition, and mutualism.

Question 4

What is Ecosystem ecology?

Answer 4

ecosystem: biological community and its interactions with the abiotic world: how energy flow and nutrient cycling are important

Question 5

Nutrient/carbon cycle

Question 6

Reductionism/Holism

Answer 6

• Reductionism: seeking answers lower in the hierarchy. (example: seeing a doctor): physiological level: studies the PARTS, rational
• Holism: seeking answers at the same or a higher level of hierarchy. Studies the WHOLE, more creative

Question 7

Darwin

Answer 7

Famous for providing a plausible mechanism for evolution. Theory: organisms within species vary in traits to due to genes and envir, populations have the capacity to over-reproduce: some survive to rep, some dont: survivors pass genes

Question 8

introduced vs local populations

Answer 8

• Local populations outperform foreign populations (in the context of fish stocking)
• Fish farms: escaped fish threaten wild fish populations by interbreeding and overtaking native species.

Question 9

what does natural selection act on?

Answer 9

individuals within populations
