Vocabulary
An environment that provides the things an organism needs to live, grow, and reproduce.
What is a habitat?
The study of how organisms interact with each other and their environment.
What is Ecology?
The number of births per 1,000 individuals for a certain time period.
What is a birth rate?
What is a Niche?
The role of an organism in its habitat is called its niche. A niche includes what type of food the organism eats, how it obtain this food, and what other organisms eats it.
The community of organisms that live in a particular area, along with their nonliving surroundings. This includes abiotic and biotic factors.
What is an ecosystem?
A non-living part of an organism's habitat.
What is Abiotic Factors?
The movement of individuals into a population's area.
What is the Immigration?
What is Natural Selection?
The process which organisms that are best adapted to their environment are most likely to survive and reproduce.
A relationship between two species in which one species benefits and the other is neither helped nor harmed.
What is commensalism?
What does an organism get from its Environment?
An organism gets food, water, shelter, and other things it needs to live, grow, and reproduce from its environment.
The number of individuals in an area of a specific size.
What is population density?
How do Adaptations help an Organism survive?
Every organism has a variety of adaptation that are suited to its specific living conditions and help it survive.
Define Parasitism and give an example.
Parasitism is a type of symbiosis in which one organism live with, on, or in a host and harm it.
An inherited behavior or physical characteristic that helps an organism survive and reproduce in its environment.
What is Adaptations?
What are the two parts of an organism's Habitat?
An organism interacts with both the living (Biotic Factor) and non-living (Abiotic Factor) parts of its habitat.
How do Populations change in size?
Populations can change in size when new members join the population or when members leave the population.
Two major types of interactions among organisms
What are Competition and Predation?
An interaction in which one organism kills another for food.
What is predation?
The series of of changes that occur in an area where no soil or organisms exist.
What is Primary Succession?
How is an Ecosystem Organized?
The smallest level of organizations is a single organism, which belongs to a population that includes other member of its species. The population belongs to a community of different species. The community and abiotic factors together form an ecosystem.
What factors limit population growth?
Some limiting factors for population are weather conditions, space, food, and water.
What are the Three types of Symbiosis?
What is Mutualism, Commensalism, Parasitism?
A group of organisms that are physically similar and can mate wit each other and produce offspring that can also mate and reproduce.
What is a species?
