This study stack contains info on biomes, ecosystems, food chains and food webs.

Energy Comes from the sun. It is required by all living things for life.
Matter The materials that make up living organisms. It is recycled over and over again.
Energy Pyramid A diagram that shows how energy moves from one trophic level to another.
Trophic Levels The different feeding levels in an ecosystem.
Food Chain The trophic levels that show one set of feeding relationships.
Food web All of the feeding relationships in an ecosystem; interrelated food chains.
Biomass The amount of matter in a trophic level. The total mass of organisms in a given area or volume.
Biomagnification The accumulation of poisons that takes place from one trophic level to the next.
Niche An organism’s place in a community (job).
Interactions The relationships between organisms within an ecosystem.
Chemosynthesis The process in which producers make energy rich nutrients from chemicals.
Riparian A freshwater river ecosystem.
Symbiosis Any close relationship between species in a community.
Mutualism Both species benefit.
Commensalism One organism benefits and the other is unaffected.
Parasitism One species benefits and the other one is harmed.
Consumers Organisms that need to eat other organisms to get energy.
Producers Organisms that produce their own food by using energy from the sun.
Herbivores Animals that only eat plant matter.
Carnivores Animals that eat meat.
Decomposers Organisms that break down dead material and return the nutrients to the soil.
Omnivores Animals that eat both meat and plants.
Predator The organism that hunts other organisms for food.
Prey The organism that gets eaten by others for food.
Cooperation Organisms work together with each other to improve the survival of both.
Competition When organisms struggle, or fight one another for mates, food, territory, space and shelter.
Abiotic Factors The non-living parts of an environment. Rocks, soil, temperature, sunlight, water, etc.
Biotic Fators The living parts of an environment.
Community All of the populations in an ecosystem.
Population All of the organisms in an ecosystem that are part of the same species.
Habitat The place in which an organism lives.
Ecosystem All of the organisms living in an area and the non-living features of their environment.
Ecology The study of interactions that occur among organisms and their environment.
Biosphere The part of the Earth that supports life.
Limiting Factor Anything that restricts the number of individuals in a population.
Name some examples of limiting factors. Can be Living and non-living features of an ecosystem. Availability of food, water, living space, mates, nesting sites, etc.
Carrying Capacity The largest number of individuals of a species that an ecosystem can support over time.
The Carbon Cycle Describes how carbon molecules move between the living and nonliving world.
The Nitrogen Cycle The transfer of nitrogen from the atmosphere to the soil, to living organisms and then back to the atmosphere.
The Water Cycle The movement of water through the environment via transpiration, precipitation, evaporation, and condensation.
Nitrogen Fixation A process through which some types of soil bacteria can form the nitrogen compounds that plants need.
Biomes Large geographic areas with similar climates and ecosystem.
Which biome in temperate and tropical regions with 25cm-75cm of precipitation a year? It is dominated by climax communities of grasses. It is ideal for growing crops and raising cattle and sheep. Grasslands
Which biome usually has four distinct seasons, an annual precipitation between 75cm and 150cm, and climax communities of deciduous trees? Temperate Deciduous Forest
Which biome is the most biologically diverse biome, has an average temperature of 25 degrees C and receives between 200cm and 600cm of rain each year? Tropical Rain Forest
Which biome receives 200cm to 400cm of precipitation each year with average temperatures between 9 degrees C and 12 degrees C? The forests are dominated by trees with needle like leaves. Temperate Rain Forest
Which biome is cold, dry, treeless and receives less than 25cm of precipitation of each year? It has a short growing season, permafrost, and winters that can be 6 to 9 months long. Tundra
Which biome is the world's largest biome and is located south of the tundra between 50 degrees N and 60 degrees N? It has long cold winters, precipitaion between 35cm and 100cm each year, cone-bearing evergreen trees and dense forests. Taiga
Which biome is the driest biome on earth with less than 25cm of rain a year? It has dunes or thin soil with little organic matter. It has plants and animals specially adapted to survive extreme conditions. Desert
Which marine biome has barnacles, ghost crabs, wading shorebirds, and periwinkles? Seashore
Which marine biome is an important nursery area for many species of ocean fish and shellfish? Estuary
Which marine biome is divided into zones based on the depth sunlight reaches? Open Ocean
Which marine biome contains colorful fishes and a variety of other animals? Coral Reef
Which marine biome has tides affect the temperature, salinity, and moisture for animals living in it? Seashore
Which marine biome has whales, sea turtles, dolphins and plankton are found in it? Open Ocean
Which marine biome has too many nutrients washing in from rivers causes harmful algae blooms? Estuary
Which marine biome is formed from calcium carbonate shells, the remains of small filter feeding animals? Coral Reef
Examples of this marine biome are Atlantic, Pacific, Arctic, and Indian. Open Ocean
Which marine biome has environmental threats such as human development and pollution being washed ashore? Seashore
These aquatic biomes are characterized by still water, deep cool, low nutrients, plants only grow along the edge, home to large fish, geese and beavers. Lakes
These aquatic biomes are characterized by still water, shallow, high nutrients, plants grow across the bottom. Home to dragonflies, frogs and ducks. Ponds
These aquatic biomes are characterized by slow moving water, warm, high nutrients, home to shad, catfish, bass and muskrats. Rivers
These aquatic biomes are characterized by little to no salinity, fast moving water, high oxygen, low nutrients, home to crayfish and fly larvae. Streams
These aquatic biomes are wet part or all of the year, can be fresh or salty, cattails or grasses, home to ducks, snails or wading birds. Wetlands
Sun-->grass--> grasshopper--> frog--> snake What is this an example of? Food Chain
In a food chain and food web, which way are the arrows moving? The direction that energy is moving.
Consumers living in the hydrothermal vent communities rely on what type of producers because of the lack of sunlight? Chemosynthetic bacteria
What is the vocabulary word for the mass of all the living and dead organic matter in an ecosystem? Biomass
Photosynthesis The process in which producers convert light energy into the chemical energy of sugar molecules.
The bottom layer of an energy pyramid represents which organisms? The producers
