What is a food web?
100
A consumer-resource interaction. One species is harmed while the other benefits.
What is parasitism?
100
This type of interactions can cause evolutionary change in two or one of the affected organisms, alter the distribution of the species, and cause a change in the populations densities
What is interspecific interactions?
100
_____ increase their population logistically, _____ increase their population exponentially. (In order)
What are K-strategists and R-strategists.
100
Most energy enter a community through this type of organism
What is a photosynthetic organism?
200
Organisms that consume a secondary consumer, or primary carnivore.
What is a tertiary consumer?
200
A heterotroph that consumes and obtains its energy from a primary producer.
What is a primary consumer?
200
A change in this can result from intraspecific competition and directional selection
What is carrying capacity?
200

What is an R-strategist?
200
This is The total amount of energy a producer converts during a specific period of time
What is gross primary productivity?
300
A model assembled in a triangle. It's shows the flow of energy with the largest biomass of energy at the bass
What is an energy pyramid?
300
The number of species in a community and the number of organisms in those species.
What is the species composition?
300
This is what happens when a predator continues to evolve their offense while the prey also evolves their defense, neither of them get anywhere and while they may be stronger, they're at the same the same distance apart.
What is an "evolutionary arm race"
300
Take better care of their young and have evolved to be better at resourcing limited parts of their enviroemy.
What is a K-strategist?
300
The amount of biomass that goes on to each increasing tropic level. In other words the percentage of biomass that each level has from the level that it feeds on.
What is 10 percent?
400
Responsible for the majority of "recycling" in a community.
What is a decomposer or detrivore?
400

What is the photic zone?
400
Native species lack adaptions to protect themselves against "newcomers", or invasive species, and often experience harm from the invader. This is one way they affect the native species positively.
What is provide resources that were not always available in that area?
400
This type of growth exhibits a "J-curve" when projected on a graph.
What is exponential, or an R-strategist?
400
A pattern caused by effects of consumer-resource interactions crossing tropic levels.
What is a tropic cascade?

What is they attack other native species?

5 differences between R and K strategies
(Possible answers) K-strategists are more stable, grow logistically, produce fewer offspring, invest more into each offspring's success, have longer life spans, begin breeding later in life, and take better care of young. R-strategists grow exponentially, have shorter life spans, breed earlier in life, produce more offspring, show less care to individual offspring.
