Transcript of Tropical Dry Forest

Biome Project: tropical dry forest By: Grant Hall Location: Tropical dry forests are found between 10 and 20 degrees North Areas where they are found include India, West Africa, Chile, Southern Africa, South America, Central America, and Northern Australia. CLIMATE Tropical dry forests have alternate wet and dry seasons The soil is rich but is often eroded It is affected by high and low pressure systems The most rainfall occurs in June and July.
The least occurs in December-March. Dominant Wildlife Plants: Columnar cacti agaves, deciduous trees, drought tolerant orchids and bromeliads, aloes Animals: Tasmanian devils, American alligators, kangaroo rats, shrews, parrots, tigers, vulture and buzzards, elephants, rhinoceros, hog deer, spotted bill pelicans, monkeys Endangered: Ocelot

This species is in danger of extinction due to deforestation and the destruction of its habitat. Its litter size is very small, so its reproduction can't keep up with how fast its environment is being destroyed. Predation: Tigers and Hog Deer

The tigers hunt, kill, and eat hog deer. Adaptation: Kangaroo Rats

Kangaroo rats breed year round
and produce about two litters a
year. This is an adaptation they
have had to make due to their
position in the food chain. They are
eaten in large numbers so they
must reproduce in large numbers. Commensalism: Birds and Trees

Birds use trees as a place to nest
and as a place of shelter. The trees
are not affected in any way by this,
so it is commensalism. Mutualism: Ant and Acacia Tree

The ants live in the thorns of the
tree and eat the sweet secretions it
produces. In return, the ant provides
protection. When anything touches the
tree the ants attack it and release a foul
odor. Parasitism: Ticks on Monkeys

Ticks live on monkeys and suck
their blood for food. Human impact Poaching is the biggest human impact in the tropical dry forest. Poachers hunt elephants for the ivory, tigers for their skins, rhinos for their horns, and even gorillas for their hands. These poachers are seriously affecting the population and health of these animals to a drastic extent. Resources

The monkey eats small birds. The small bird eat berries. The berries come from a plant that gets its energy through photosynthesis from the Sun.
