Define Mutualism
Mutualism- a symbiotic relationship where both/all species benefit.
100
In a predator-prey relationship, how does an advantage affect survival chances?
An advantage always increases the chance for survival.
100
Define species richness
Species richness- the total amount of species in a community.
100
Define pioneer species
Pioneer species- the species of organisms that predominate early in succession.
100
Is there ONE single set pathway to get to the climax community in succession?
No, there is not. (But the patterns of succession are relatively predictable).
200
Define commensalism
Commensalism is a symbiotic relationship in which one species benefits and the other is not affected.
200
What are the two categories for adaptations?
Predator adaptations and prey adaptations.
200
Define disturbance
Disturbance- events that change communities, remove or destroy organisms from communities, or alter resource availability.
200
Define ecological succession
The gradual, sequential regrowth of a community of species in an area
200
What are the two broad categories of predation?
Herbivory and Carnivory

Name the 3 types of symbiotic relationships. (symbiosis)
Parasitism, mutualism, commensalism
300
Predator adaptations help the predators to do what 3 things?
Help predators to find, capture, and consume their prey.

Two islands are located close to each other and at about the same latitude. Island A is much larger thand island B. Which is more likely to have more species and WHY?
Island A is more likely to have more species (higher species richness) because it is larger, which means it can probably support more life.

Species A has an advantage over species B. hat will likely happen to species B in a competition relationship between species A and B?
Species B will reduce in population size or may even be eliminated.
400
Prey adaptations help the prey to do what 3 things?
Avoid, escape, and ward off predators.
400
What pattern is observed between the values for latitude and species richness?
The closer to the equator an ecosystem is, the higher species richness it is likely to have.
400
What is the main difference between primary succession and secondary succession?
The presence of usable soil in secondary succession.

Give an example of a commensalism relationship that you do or could have with another species. (what is a way that you can benefit an individual from another species without it benefiting you?)

Why is the mutualistic relationship that happens for pollination important for humans?
The relationship is important for humans because we get food and oxygen (and medicine) from the plants that use pollination. Without this mutualist relationship, plants would die and then animals would die, which means we would die.

Why does primary succession usually proceed slowly?
The lack of usable soil at the beginning makes the process slow because soil must be built up over time in order to allow for succession to continue.

How is species richness related to biodiversity?
They are directly proportional. Higher species richness= higher biodiversity.
