Ecology Ecology is the study of interactions between organisms and the living and non-living components of their environment. It involves collecting information about organisms and observing their life patterns as well. Ecology is a science that seeks to explain why patterns occur the way they do. Interdependence is a key component of biology‚ meaning that all the organism interact with one another in various ways. Its very crucial for organisms since they all depend on one another

➢ Competing – Two species compete with another species for resources such as food‚ water‚ or territory ➢ Biomes – major types of ecosystems that occupy very broad geographic regions. ➢ Photic zone is where there is enough light for photosynthesis to occur and an aphotic zone‚ where very little light penetrates. ➢ Benthic zone - is located at the bottom of the biome ➢ Oligotrophic lakes are deep lakes that are nutrient-poor and oxygen-rich and contain sparse phytoplankton.

Tropical evergreen forest Tropical forests are characterized by the greatest diversity of species. They occur near the equator‚ within the area bounded by latitudes 23.5 degrees N and 23.5 degrees S. One of the major characteristics of tropical forests is their distinct seasonality: winter is absent‚ and only two seasons are present (rainy and dry). An evergreen forest is a forest consisting entirely or mainly of evergreen trees that retain green foliage all year round. Such forests reign the tropics

Acknowledgement Contents Introduction A savanna‚ or savannah‚ is a grassland ecosystem characterized by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses.[1][2][3] The oak savanna is a common type of savanna in the Northern Hemisphere. Some classification systems[which
