TOPIC 1
A population’s size also can increase or decrease when individuals move into or out of the
population this is called:
Immigration and Emigration.
States that matter is neither created nor destroyed during any Physical or Chemical change:
Law of Conservation of Mass
Condensing water vapor collects as clouds, but as the drops continue to grow larger, the become heavier, eventually, they fall in the form of:
Precipitation
States that when one form of energy is transformed to another, no energy is lost in the process:
Law of Conservation of Energy
Consumers that eat only animals are:
Carnivore
Causes a population to stop growing or to decrease in size.
Limiting Factors
This becomes the source of energy for other organisms in an ecosystem. They can make its own food.
Producers
Obtain energy by feeding on other organisms.
Consumers
The parts of a habitat that are or were once alive and that interact with an organism.
Biotic Factors
Most organisms take this in from air or water and use it to carry out cellular respiration:
Oxygen
An environment that provides the things a specific organism needs to live, grow, and reproduce.
Habitat
Consumers that eat only plants are:
Herbivore
Are based on the way organisms obtain food and interact with other organisms.
Energy Roles
Factor that limit population growth:
Food, Water, Weather, Space and Shelter
Consist of many overlapping food chains in an ecosystem.
Food Web
Is a series of events in which one organism eats another and obtains energy and nutrients. Food
Chain
All the members of one species living in a particular area are referred as.
Population
The community of organisms that lives in a particular area along with the nonliving environment, makes up an:
Ecosystem
All the different populations that live together in an area make up a:
Community
Is the process by which molecules at the surface of liquid water absorb enough energy to change to a gas.
Evaporation
The largest population that an area can support is called:
Carrying Capacity
Are the nonliving parts of an organism’s habitat.
Abiotic Factors
Consumers that eat both plants and animals are:
Omnivore
The process of a gas changing to a liquid:
Condensation
Shows the amount of energy that moves from one feeding level to another in a food web.
