Where is savanna grassland

Animals may migrate great distances in search of food and water. The graph below shows average monthly temperatures and rainfall levels in the savanna region of Mali. Notice how the temperature and rainfall patterns relate to each other - the hottest temperatures come just before heavy rainfall, and the coolest time of the year comes just after the rains. This pattern is typical of savanna climates. If a media asset is downloadable, a download button appears in the corner of the media viewer.

Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. Producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid. Primary consumers, mostly herbivores, exist at the next level, and secondary and tertiary consumers, omnivores and carnivores, follow.

At the top of the system are the apex predators: animals who have no predators other than humans. Help your class explore food chains and webs with these resources. A biome is an area classified according to the species that live in that location. Temperature range, soil type, and the amount of light and water are unique to a particular place and form the niches for specific species allowing scientists to define the biome.

However, scientists disagree on how many biomes exist. Some count six forest, grassland, freshwater, marine, desert, and tundra , others eight separating two types of forests and adding tropical savannah , and still others are more specific and count as many as 11 biomes. Use these resources to teach middle school students about biomes around the world. A biotic factor is a living organism that shapes its environment.

In a freshwater ecosystem, examples might include aquatic plants, fish, amphibians, and algae. Biotic and abiotic factors work together to create a unique ecosystem.

Due to its open environment, camouflage and mimicry are essential for animal survival in the savanna.

Savannas have extreme wet seasons and dry seasons. They can receive over four feet of rain during the wet season, and as little as a few inches during the dry.

Due to this lack of precipitation, it is very difficult for large plants like trees to grow in savannas. While savannas are located on six of the seven continents, the largest are found in equatorial Africa.
