characteristic plant and animal community

A biome is identified by its particular set of abiotic factors and its ——-

mutualism

A symbiosis in which both species benefit is

anthropogenic

A —————— ecosystems is one that has been drastically altered by human contact like agriculture

biotic factors

All of the living organisms in an ecosystem represent the

food web

All the interlinking feeding relationships in an ecosystem make up a

Predation

An interaction in which one organism captures and feeds on another organisms is called

Nitrogen fixation is carried out primarily by ———— on plant roots

Decomposers

Organisms that obtain nutrients by breaking down dead and decaying plants and animals are called

estuary

The Mississippi Gulf Coast is one of our most valuable resources. It is place where fresh and salt water mix, being loaded with nutrients. This area is very valuable nursery group for fish and other aquatic animals like shrimp. Which term is used to describe this area correctly?

Ecology

The branch of biology dealing with interactions among organisms and between organisms and their environment is called

ecosystem

The combined portions of Earth in which all living in thins exist is called the

pioneer species

The forestry industry in Mississippi provides many jobs across the state. When a company clear cuts a tract of timber,all trees and vegetation are removed leaving bare ground. Grasses begin to grow shortly afterward. The grass represents a

water

The hydrosphere represent the parts of the biosphere that are

migration

The mallard duck is one of the most abundant species of waterfowl in the US. They spend the summer months in the prairie potholes of southern Canada and northern central US. During the3 colder winter months, millions fly down the Mississippi flyway located along the Mississippi RIver and our delta region to spend feeding in flooded timber and flooded fields. WHich term best describes this behavior?

rhythmic patterns

The rise and fall of the tides is an example of

succession

The series of predictable changes that occurs in a community most notable in plant species over time is called

Community

The simplest grouping of more than one kind of organisms in the biosphere is?

Biomass

The total amount of living tissue witching a given trophic level is called the

tropical rain forest

This biome found along the equator in like South America and parts of Africa is hot, wet year-round, plants broad-leafed, animals like monkey and toucans are found here

Deciduous forest

This biome found here in Mississippi has cold to milder winters, warm summers, year-round precipitation, plants like oaks and pines flourish, animals such as whitetail deer, squirrels and songbirds live here

Coniferous forest

This biome found in Northwestern U.S. and parts of Canada is characterized by abundant rainfall, mild winters and cool dry summers, plants like the giant redwood, spruce trees, and ferns grow well, animals such as bears, black tail deer, and the mythical Bigfoot live here.

Savanna

This biome found in parts of Africa is characterized by lush grasses and scatters acacia trees. Animals such as antelope, lions, zebra, and elephants are common. IT has very seasonal rains and is usually very warm

Desert

This biome found in parts of the western US and the Sahara region of African is very hot receiving very little rainfall, plants like cacti and succulents grow, animals such as mule deer, rattlesnakes and kangaroo rats live there.

Grassland

This biome found in the Great Plains region of the US has cold winters, warm summers, season precipitation, very fertile soils, plants like lush grasses grow in plenty, animals like prairie dogs, badgers, and pronghorn flourish.

Chaparral

This biome found in the southwestern US is characterized by scrub brush usually bordering deserts and mountain ranges. Animals such as the rattlesnake, roadrunner, and coyote are common. Climate is dry, hot, with cold nights

Tundra

This biome found int the northern parts of Canada, Alaska, and northern Asia is characterized by a layer of permanently frozen subsoil called permafrost, high winds, very cold temperatures, plants such as mosses and lichens grow very close to poor nutritional soil, animals life caribou, Arctic foxes, polar bears and the mush ox live here

Trophic level

omnivores

What animals eat both producers and consumers?

herbivore

What is an organism that feeds only on plants called

the result of an excess of carbon dioxide in the atmosphere

What is the greenhouse effect?

Sunlight

What is the original source of almost all the energy in most ecosystems?

nitrogen fixation

What is the process by which bacteria convert nitrogen gas in the air to ammonia?

annual

When the Department of Wildlife, Fisheries, and Parks of mIssissippi sets the whitetail deer season to occur during October through the end of January, this is done to coincide with their breeding season. The reproductive cycle presents which type of rhythmic patterns?
