How does grass grow back after being cut?

Answer 1

Animals are able to survive the dry conditions of the grasslands using their adaptations as well. They are able to acquire water even when little is available. Some herbivores, like antelope, eat at night when foliage has the most water in them. These animals also receive the water from dew that is on the leaves at this time of day. The black rhinoceros chews succulent leaves, leaves that are protected from water loss. Then they spit out the left over fibers. The hyrax gets almost all its water from plants. Other animals that are fortunate enough to find a water source may obtain water from a river bed or waterhole. Larger animals, such as elephants, may dig into the earth to reach sources of underground warer making a kind of "well." Other animals that live near these animals may use this water, too. Animals are able to satisfy their need for water in this dry habitat. Along certain areas of North America and Eurasia you will find grassland biomes. There are mountain ranges in place that prevent the ocean air masses from affecting these areas. As a result the polar air can become dominant, giving way to some colder temperatures in the winter months. However, in the summer the continental air mass is dominant. As a result there is some rainfall during the summer. You will find grassland biomes in the middle latitudes. Those that have oceans close by get more rain. They also have colder winters. However, there are those grassland biomes such as around Siberia that are extremely cold and windy. This is because they don't have the mountains around to help break the wind. They are found in North America, South America, Australia, New Zealand, and Africa.

The temperatures can be from -40 degrees in the winter to about a comfortable 70 degrees in the summer. There are two seasons here -- the growing season and the dormant season. During the dormant season nothing is able to grow due to the very cold temperatures. You may be surprised to learn that there can be 6 feet or more of snow on the ground during the winter months in the grassland biome.

The grassland biome is considered to be a transitional location. They are found between the desert and the forest biomes. If there was more rain, they would be considered a forest biome. However, if there was less rain it would be a desert biome. This is why the issues of global warming are very serious for this particular biome. It is also why so many people often overlook this particular biome as being a separate entity.

The summer months are very hot in a grassland biome. They are also very cold in the winter months. The grassland biomes are very large areas. You will find them full of herbs, grass, and flowers. There can also be trees in small areas, but they will be spread out rather than close together like they are in most other biomes. The soil is very thin in this biome though so these aren't trees that are wide and tall. They are very thin and small.

There is enough precipitation in a grassland biome to support such living things. You may often hear it referred to as the prairie. There are two different climates found in a grassland biome. Some of them offer tall grass and the area is very wet. The grass in these areas can be up to 5 feet tall. There is also a great deal of humidity in this area. The second option is an area that offers short grass and it is dry. The grass may barely peak above the ground.

In many areas there can be an in between of both the tall and short grassland biome characteristics. This is typically referred to as the mixed grasslands. They tend to have grass that is about 2 or 3 feet tall. The terrain and climate in these different areas can affect how tall the grass will be. The amount of rainfall is also a contributing factor.

It is believed that there are at least 80 species of animals that live in the grassland biome. There are over 300 species of birds that either permanently live there or that migrate in and out of the area. There are hundreds of different types of plants that are known to grow in this particular type of biome. The animals that live here have learned how to adapt to the dry conditions and the wind.

There is quite a bit of diversity found among the animals living in the grassland biome. They include those that burrow under the ground, those that graze and eat the grass, and those that consume other animals that live in this biome. It is a cycle of life that is evident here for all to benefit from.

You will find lots of great hunters out there in the grassland biome. They include the coyote, bobcats, and Gray Wolf. There are also quite a few plant eating animals out there. They include the Bison, Prairie Chicken, and Crickets. There are also numerous birds such as Canadian Geese and Eagles.

The most common types of plant life in the Grassland biome include Buffalo Grass, Crazy Weed, and Wild Indigos. Such plants offer plenty of food sources for various animals that live in this biome. There are also plenty of meat eating animals that live here too. They are going to consume those animals that are plant eaters.

There is a very delicate balance in the grassland biome between the plants and the animals. They all depend on each other for survival. During an extended drought season, plants and grass may not grow as plentiful as it should. That can result in many animals that depend on those food sources starving. That can also mean less prey for the meat eating animals that live in the grassland biome.

Answer 2

• During a fire, while above-ground portions of grasses may perish, the root portions survive to sprout again
• Some prairie trees have thick bark to resist fire
• Prairie shrubs readily re-sprout after fire
• Roots of prairie grasses extend deep into the ground to absorb as much moisture as they can
• Extensive root systems prevent grazing animals from pulling roots out of the ground
• Prairie grasses have narrow leaves which lose less water than broad leaves
• Grasses grow from near their base, not from tip, thus are not permanently damaged from grazing animals or fire
• Many grasses take advantage of exposed, windy conditions and are wind pollinated
• Soft stems enable prairie grasses to bend in the wind

Answer 3

In a grassland, most plants (such as prairie grass) have long roots that stretch into the ground to get the most water possible. Animals have adapted to this biome by grazing (meaning they eat only grass or seeds) or burrowing to find shelter.

Answer 5

Dan and daylily answered this on Yahoo Answers. They are both interesting:

Dan's answer:

If you ever pull up a grass plant, you will see that above the root system, there is a kind of bulgy round section out of which the blades of grass grow. This is a node, where different kinds of plant cells can be created. The top of a blade of grass is constantly sending an inhibiting hormone down to the node, telling it that there is enough plant material above the node in order to support the entire plant through photosynthesis. Once the blade of grass is cut, the supply of the hormone is cut off, which triggers the node to begin creating a new leaf shoot [blade] of grass.

daylily's answer:

It grows from the crown of the plant, so new growth is constantly "pushing up". The purpose of the plant is to reproduce, so that when it's cut, it grows more to try to set seed. Once this is accomplished, growth slows. This is why, if left uncut, grass reaches its genetically programmed height and grows no higher. Correct mowing, which prevents seed formation, actually encourages lush growth.

Answer 6

Grass grows back after being cut through a process called regrowth. The remaining portion of the grass plant contains energy reserves and a growth point that allows it to regenerate new shoots and leaves. With adequate sunlight, water, and nutrients, the grass will start to grow back and eventually cover the area that was cut.

Answer 7

They eat grass an run away when there are predators?

Also, they gather in group so it's harder to get attacked.

Quiet basic stuff really

Answer 8

yes
