Population Ecology
This term describes all the individuals of the same species living together in one place at one time.
Population
This type of factor impacts a population the same regardless of size.
density-independent factor
These organisms make their own food and form the base of all food chains.
Producers
A tick feeding on a dog is this type of interaction.
Parasitism
The H in HIPPPCO stands for this major threat to biodiversity.
Habitat loss
This is the number of individuals per unit area.
Population density
Disease, competition, and predation are examples of this type of limiting factor.
density-dependent factors
Only this percentage of energy is transferred to the next trophic level.
10%
A bee pollinating a flower is an example of this relationship.
Mutualism
The I in HIPPPCO represents this biological threat.
Invasive species
This type of growth shows a J-shaped curve when resources are unlimited.
Exponential Growth
This term describes the movement of individuals into a population.
Immigration
Arrows in a food web show this.
flow of energy
A hawk catching a mouse demonstrates this interaction.
Predation
This threat involves humans removing too many organisms from an ecosystem.
Overharvesting
This S-shaped growth occurs when limiting factors slow population growth.
Logistic Growth
This term describes the movement of individuals out of a population.
Emigration
Decomposers such as bacteria and fungi play this crucial role.
recycling nutrients
Barnacles on a whale represent this relationship.
Commensalism
Ecosystems with more biodiversity are more stable because they have these.
more species to fill ecological roles (niches)
The maximum population size an environment can support long-term.
Carrying Capacity
A population decreases after a drought reduces plant growth. Identify the limiting factor type.
density-independent factor
If a person eats chicken, they are acting as this type of consumer. (specific answer needed)
secondary consumer
A decrease in prey causes a decrease in predators. This is an example of what ecological pattern?
predator-prey relationship
Explain why climate change threatens biodiversity.
because temperature and weather changes alter habitats, making them unsuitable for species that cannot adapt
