Characteristics of Life
All living and non-living things are composed of this
What is matter?
What are births or immigration?
The interaction characterized by one population consuming another population.
What is predator/prey?
The amount of different species in an area.
The role a species has in a community.
What is niche?
The smallest unit of life
What is a cell?
Two things that cause a population to decrease
What are deaths and emigration?
An interaction in which both individuals benefit.
What is mutualism?
The type of diversity that results from a worldwide variety of communities (ex. deserts, mountains, forests, etc.)
What is ecosystem biodiversity?
Federal law that protects species in danger of going extinct.
What is the Endangered Species Act?
Living things can only come from other __________________.
What is living things? (or organisms)
The type of population growth that is typically represented by a J-curve.
What is exponential growth?
A relationship in which one species interacts with another without immediately killing it, but causes harm nonetheless.
What is parasitism?
This is the variety of DNA among a species.
What is genetic diversity?
The largest number of individuals within a species that a habitat can sustain.
What is carrying capacity?
The main difference between autotrophs and heterotrophs.
What is the ability to make or consume chemical energy?
What is logistic growth?
A prey population will ___________ after the predator population decreases.
What is increase?
The variety of species in an area?
What is species diversity of species richness?
Limiting factors that rely on the size of a population (ex. amount of food, water, and shelter)
What are density-dependent factors?
The seven characteristics of life
What is energy utilization, cells, growth/development, reproduction, internal regulation, response to the environment, and evolution/adaptation? Responses may be a variation of the listed characteristics.
The differences between k- and r- strategists.
What is the speed and number of offspring produced? Response may address mortality rates, physical size of offspring, and/or age of maturation.
(K-slow and fewer, R-quick and many)
This occurs when a keystone species disappears.
What is overpopulation and crash of keystone species prey? Response may also include ecosystem instability.
A reason why biodiversity is important for maintaining the health of an ecosystem.
What is ... ?
Answers may vary.
Limiting factors that decrease the size of a population regardless of its size (ex. natural disaster)
What is a density-independent limiting factor?
