approximately 400 km off the southeastern coast of Africa in the Indian Ocean. The rainforests of Madagascar are located in very humid‚ low-elevation‚ and narrow regional strips along the east coast of the island. The Madagascar rainforest is just another ecosystem‚ it actually acts as a home to many endangered species including the silky sifaka‚ sportive lemur‚ and the red-ruffed lemur. Another very important species that is indigenous to this rainforest is the rosy periwinkle‚ which is used to cure leukemia

Species that are found in a specific area and only found in this specific place are called endemic species. Here in Florida we have several endemic species and an example of one is the great Florida Panther. The Florida Panther is also a very endangered species only a few hundred still exist. Many factors contribute to its small population such as human

Desert Biome Food Web Diagram Food Web Diagram An ecosystem can be defined as a more or less self-contained function unit in ecology consisting of all abiotic and biotic interactions in a specific area. Flow of energy within an ecosystem is a one-way process; Photosynthesis utilizes light (solar) energy to yield chemical energy that is passed on to organisms at significantly reduced amounts at

This has caused enormous growth in algae populations‚ literally choking the life out of aquatic ecosystems and polluting water for humans as well. These “Harmful Algal Blooms” (HAB’s) or green tides as some call them can produce toxins that can hurt animals and humans alike turn water green and can cover miles of water in a single bloom.

from the Greek oikos meaning "household" and logos meaning "study"; hence‚ the "study of the household of nature". E. P.

He referred to ecosystem as the basic fundamental unit of ecology. ecological science‚ is the scientific study of the distribution and abundance of

Ecosystem Components and Interactions I. Introduction An ecosystem is a complex relationship between a community of organisms and the environment that they dwell in where energy is exchanged and transformed. Ecosystem includes the biotic (living organisms)‚ the abiotic (physical and chemical factors)‚ and the interactions made between these. They continually interact with each other‚ thus making complex systems with intersecting properties wherein “everything is connected”. In ecosystem ecology

Some of these invasive creatures have caused the extinction of whole species and have caused irreparable damage to the surrounding ecosystem. For example‚ alien insects‚ organisms‚ plants cause damage to crops and forests. Some invasive fishes contributed to the disappearance of a lot of fish species through predation and competition for food. Migratory crab‚ during his mass migration

In the Alaskan Tundra‚ abiotic factors include wind‚ temperature‚ and sunlight. Abiotic factors are nonliving things that influence or affect the ecosystem and the organisms in it. Factors such as wind‚ temperature‚ and sunlight can have a lasting effect on an ecosystem such as an Arctic Tundra. In the Alaskan Tundra‚ strong and persistent winds rush through the air. These winds desiccate and abrade plant tissues‚ contributing to one of the many factors of why tundras aren’t able to grow trees.
