Texas Prairies and Lakes

Made by: Summer Moreno (plains and montain ranges), Ashley Pitts(prairies), Yaneiri Ruiz (Urban/city), Noemi Valdespino (Lakes)

Lakes:

  • Lake Fork

One of the 10 largest lakes in Texas.

Designed a premier bass fishing lake.

Surface area: 27,264 acres.

  • Lake Ray Roberts

Designed for hiking and camping.

Surface area; 25,600 acres

  • Animals

Black bears

Mountain Lions

Coyotes

Bass Fish

More than 200 species of birds

Food Chain- made of producers, primary and secondary consumers, and fungi and bacteria.

  • The Cross Timbers
  • Grand prairies
  • Rolling plains

Plains and Mountain Ranges

Bedrock Types

  • Limestone
  • Sandstone
  • Shales

Predators and Prey:

The predators are the

coyotes, foxes, and

screech owl.

The prey is the weasel,

field mice, and rattlesnakes.

Watershed:

The Brazos River branches

off as the Clear Fork River,

Double Mt Fork, and the

Salt Fork.

Animals:

  • Screech owl
  • Weasels
  • Coyotes
  • Foxes
  • Rattlensnakes

Succession:

Plains catch on fire when there hasn't

been any rain. The burning of the land

fertilzes the soil to make more grass and

other plants grow for animals to eat.

Example Food Chain:

The wasels are eaten by

coyotes or screech owls.

PRAIRIES

Prairies-

  • Oak woods and prairies
  • Upland soils are light colored, acidic sandy loam or sands. Bottomland soils may be light brown to dark gray and acidic with textures ranging from sandy loams to clays.
  • Black Land Prairies
  • Typically, soils are uniformly dark-colored alkaline clays, often referred to as "black gumbo", mixed with some gray acid
  • Organisms-
  • Armidillo
  • mocking birds (state bird)
  • wood ducks
  • cotton wood trees
  • bob cats
  • grey foxes
  • field mice(secondary producers)
  • purple love grass (primary producer)

Succession-

succession is a change in an ecosystem that

happens over time

Example-

The black land prairies had a fire in the past and many organisms died because of it. Eventually they grass and trees grew back and more animals where able to build their homes there.

Animals:

nine banded armadillo

texas horned lizard

red wolf

wood ducks

red- shouldered hawk

Population Dynamics:

Producers

  • The growth of the species in the ecosysytem. When one species breeds, the population gets larger.
  • Primary producers- Something who makes its own food. An example is a tree.
  • Secondary producers- Eats primary producers.

Cycles

  • Water- Series of flowing and stored water. 1st part is precipitation- water falling on the earth. 2nd part is evaporation- water going back into the atmosphere. 3rd part is transportation- going into the roots. 4th part is condensation- the collection of clouds.
  • Nitrogen- Starts in the atmosphere, goes into the soil, and back into the atmosphere.

1. Nitrogen fixation

2. Nitrogen assimilation

3. Ammonification

4. Nitrification

5. Deification

  • Carbon- 1st- absorb CO2 during photosynthesis, 2nd- produces glucose. Glucose moves up the food chain. Decomposers get glucose by eating dead organisms. Last stage is by humans.
  • Nutrient- Nutrient cycles are made up of carbon, water, and nitrogen cycles. All nutrients are recycled.

Watershed

  • a watershed is a place that holds water and then drains into a bigger body of water.

Climate and weather-

  • Climate is how the weather changes over time.
  • Weather is the elements we see daily, such as rain, wind, and temperature. It changes hour by hour.

Predators eat the prey.

Example: The grey fox eats the field mice.

Climate- The climate is warm temperate to subtropical and humid. Precipitation ranges from 762 mm on the western edge to 1,016 mm on the east. The weather consist of some rain throughout the year and minimal snow in the winter.

Pollution-

Oil drilling is releasing a mixture of toxic gasses into texas prairie's atmosphere.

Food chain-

Purple lovegrass>field mice> rattle snake> hawk

animals:

armadillo

wood ducks

Mockingbirds

Plains pocket gopher

Beaver

Raccoon

Porcupine

Hispid cotton rat

Vegetations:
