5th Science Ch 4 Ecosystems Biomes & Communities

ecosystem all the living and nonliving things that interact with one another
population all the members of the same type of oraganism living in an ecosystem
ecology the study of how living things and their environment interact
abiotic non-living
biotic living
community a group of living things of different species found in an ecosystem
habitat the natural environment where an organism lives
niche role of an organism in its habitat
carnivore meat eater
producers organism that makes its own food from raw materials and energy
omnivores plant and meat eaters
decomposers breaks down dead plants and animals into useful things like minerals that enrich the soil
scavengers animals that eat the remains of dead animals
predators animal that hunts and eats other animals
herbivore plant eaters
consumers organism that gets energy by eating food, not producing it
food web description of all the food chains in an ecosystem
food chain description of how energy in an ecosystem flows from one organism to another
evaporation process of a liquid becoming a vapor
condensation change of state from a gas to a liquid as energy is removed
precipitation Any form of water, such as rain, snow, sleet, or hail, that falls to the earth's surface.
transpiration evaporation through the leaves of a plant
water vapor Water in its invisible gas form
Sun primary source of energy for all living things
decomposer what food chain always ends with
rich healthy moist soil and sunlight what plants need to make food
weather affects habitat
erosion affects habitat
symbiosis close, longstanding relationship between species
decomposer fungi, bacteria
precipitation rain, snow, sleet
primary consumers in an energy pyramid insects, rabbits, mice, small fish
second level consumers in an energy pyramid frogs, larger fish
third level consumers in an energy pyramid eagles, lions, snakes
food web shows overlapping food chains in an ecosystem
heat what is lost at each step of the food chain
energy __________ is transferred from one organism to another in the food web.
biome a large group of ecosystems that have similar characteristics
climate refers to the type of weather that occurs in an area over a long period of time
tropical rain forest very rainy and hot
high moisture and warmth why more kinds of plants and animals live in tropical rain forest than any other biome
temperate forest experiences four distinct seasons;
grassland has distinct dry season; trees are few and far between
grassland prairies and savannas
desert driest biome; contain little life
taiga long, severe winters and short, cool summers; fairly dry
tundra earth's coldest biome; has frozen ground; near the arctic circle
temperate forest what type of biome is Alabama
marine biome near or on the ocean shore
freshwater ecosystem streams, rivers, ponds, lakes, and wetlands
marine biomes salty
herbivore eats only producers
population zebras are an example of a(n) ____ of living things in an ecosystem
food chain the flow of energy from producer to first level consumer to second level consumer can be shown using a simple _______
climate temperature and precipitation determine the _____ of an area
permafrost frozen ground found in tundra
temperate rain forests trees that lose their leaves in cool fall weather are common in ___________
energy about 10 percent of the ________ available at one level of an energy pyramid passes to the next level
Symbiosis is a situation in which 2 different organisms live together in close association
Mutualism is when both organisms benefit from the relationship. In this picture, ants are living in an young acacia plant.
Parasitism is when one organism benefits and one is hurt by the relationship.
Commensalism is a relationship in which one organism benefits and the other is not affected. Orchids can illustrate this.
