A population is a group of organisms in one general area. An example of a population is humans.
A community is many organisms interacting and working together in the same environment.
Something formed when a group of organisms in a community interact with one another in an environment. An ecosystem consists of plants, animals, and abiotic and biotic factors, in which they all depend on each other to live.
A desert is an area that has little rainfall and only can either support sparse and far spaced vegetation or none. A desert is normally barren or not very lively. For instance, the Sahara Desert.
Examples of Tundras are; arctic, plain, etc.
A marine biome is a biome that is located in an ocean and is filled with saltwater. A marine biome is not the same as a freshwater biome. Marine biomes cover as much as three-fourths of the Earth's surface. Including, reefs, oceans
A food chain can be described as the energy flow between organisms. A food chain is all about a sequence of who consumes who to survive. The order in a food chain from the bottom up is;
A secondary consumer is an animal that consumes energy off of other consumers. Yet, the biggest prey of a secondary consumer is a primary consumer. A secondary consumer is considered a carnivorous animal. However, they can also be omnivores. They prey off of animals and plants. For example, a Jaguar, Caiman, Pacman Frog, Flying Squirrel, and a Harpy Eagle. Secondary consumers are towards the top of the food chain, rather than the bottom.
Biodiversity means differences within plants and animals in their environments. Biodiversity is often used to measure the health of an ecosystem. There are three types of biodiversity. They are genetic, ecosystem, and species biodiversity.
Genetic biodiversity is the difference between individuals of a similar species. For instance, cats are a big species. However, there are many different types of cats like; calico, siamese, short-haired, etc. They are all different in their appearance and genes, and genetic biodiversity finds out how that all is.
Species biodiversity is the variety of species in different area. Species biodiversity is determined by finding the taxonomic diversity or just plainly counting the number of species.
Ecosystem biodiversity is the measure between the boundaries of an ecosystem. However, it is very diffuicult to measure ecosystem biodiversity because the boundaries are not easily seen within ecosystems.
An endangered species is a species in fear of becoming extinct. This could be due to human interference like hunting, construction, or pollution. A species could also be endangered because of a climate or major temperature rise or fall. Also, a major difference in the predator and prey ratio could result in an endangered species.
