Question

The chart shows characteristics of a biome. Less than 25 cm rain per year Animals are mostly active at night Plants have widespread roots to take in water quickly Which biome is being described? Question 4 options: Savanna Tundra Desert Tropical Rainforest

Answer 1

Answer:

Desert

Explanation:

A biome can be defined as a portion of the biosphere with distinct flora and fauna with respect to abiotic factors such as temperature, rainfall, topography, etc. They play important roles in the sustenance of life on earth.

The major types of biomes that exist in the world include:

• Desert biomes
• Tundra biomes
• Aquatic biomes
• Forest biomes
• Grassland biomes

The desert biomes are characterized by very little or no rainfalls with high temperature, low atmospheric moisture and low vegetation cover. Because of the high temperature and sun intensity, animals within deserts are mostly active at night in order to prevent desiccation.

Plants within the desert have also adopted some adaptive attributes in order to cope with the harsh conditions. These adaptations include having extensive roots that take in water quickly when available, possession of modified leaves to prevent excessive water loss due to evapotranspiration, etc.

The biome being described in the question is desert.

Answer 2

Answer:

Desert

Explanation:

Desert rainfall is 25cm per year. Animals are active at night to avoid dehydration,from the extreme temperature,  they burrow into the soil during the day to avoid the heat.Plants have widespread roots to  tap water from wide areas. The leaves are long and narrow to  reduce the surface available for transpiration therefore conserving water.

Generally desert biome is characterised with low rainfall, high sunlight.They cover about 20 % of the earth landmass.  They can be divided into four categories'hot, dry, semiarid, coastal and cold.
