Population
What are a group of organisms of the same species that inhabit a specific area at the same time (ex: white tailed deer in forest).
The link between living things and nonliving things is that they are all part of a vast and interconnected system.
What is Biosphere?
Producers get their energy from the sun.
True
What is the coldest biome on Earth? a.) tundra b.) desert c.) rainforest d.) grasslands
a.) tundra
List 3 examples of animals that live in the tundra
lemmings, foxes, caribou, hares, migratory birds
Community
Is the combination of all populations of different species that share the same area. The sum of all animals, plants, algae, fungi, and microorganisms that live in a pond makes up the community.
The study of the connections of living things to each other and to the physical parts of their environment.
What is Ecology?
Consumers get their energy from several different food sources within the ecosystem.
True
The simplest model of energy flow through an ecosystem, shows "who eats whom," or feeding relationships: a.) food chain b.) trophic level c.) apex predator, d.) food webs
A.) Food Chain
list 3 animals in the temperate deciduous forest
owls, chipmunks, squirrels, raccoons, foxes, badgers, deers, bears
Photosynthesis
Process by which plants make food, uses sunlight to convert carbon dioxide and water into sugars and starches.
Is a system of interactions among a living community of species and the nonliving environment.
What is an Ecosystem?
Some life on earth requires energy to survive.
False, ALL life on earth requires energy to survive.
Mathematical models that show the flow of energy and matter in an ecosystem, with trophic levels stacked one on top of the other. a.) food webs b.) ecological pyramids c.) food chain d.trophic levels.
b.) ecological pyramids
List an example of an organism in each trophic level.
Plankton, guppy, jellyfish, turtle, shark
Autotrophs
Organisms that make their own food, also known as producedures.
The living parts of an ecosystem, such as bacteria to the largest animals, that live in the same environment.
What is biotic factors?
Decomposers consume animals that are already dead such as vultures.
False; scavengers
Matter that flows through cycles, these cycles recycle chemical elements, or nutrients, within ecosystems. a.) water cycle b.) biochemical cycle c.) nitrogen cycle d.) transpiration cycle
b.) biochemical cycle
List the 5 Ecological Levels of Organization
Organism, Population, Community, Biome/Ecosystem, Biosphere
Models
What are representations that can be used to study systems and their interacting parts.
The nonliving things in an ecosystem. They are the physical and chemical components of an ecosystem that determine which types of organisms can thrive in that environment.
What are abiotic factors?
Scavengers are organisms that eat the bits of organic matter left behind by decomposers such as earthworms, or may eat other decomposers.
False, DETRITIVORES
A process where special bacteria that use powerful enzymes to convert atmosphere nitrogen into ammonia. a.) fixed nitrogen b.) nitrogen fixation c.) denitrification d.) nitrogenation
b.) nitrogen fixation
6 major terrestrial land biomes
tundra, desert, rainforest, grasslands, temperate deciduous forest, coniferous forest
