The biosphere is the global sum of all ecosystems. It can also be called the zone of life on Earth‚ a closed (apart from solar and cosmic radiation)‚ and self-regulating system.[1] From the broadest biophysiologicalpoint of view‚ the biosphere is the global ecological system integrating all living beings and their relationships‚ including their interaction with the elements of the lithosphere‚ hydrosphere‚ and atmosphere. The biosphere is postulated to have evolved‚ beginning through a process of biogenesis or biopoesis

1. Define ecology. Identify the two features of organisms studied by ecologists. Ecology is the scientific study of the interactions between organisms and the environment‚ which in turn determine both the distribution of organisms and their abundance. Ecologists study how interactions between organisms and the environment affect phenomena such as the number of species living in a particular area‚ cycling of nutrients in a habitat‚ and the growth of populations. 2. Describe the relationship between

➢ 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.

The tropical rainforest and tropical savannah are two of the ten major global terrestrial biomes of the world. While they are both located on or near equatorial regions‚ varying differences in climate‚ biodiversity‚ ecology‚ and soils characterize each region. Even though both are under the larger categorization of being “tropical”‚ the similarities end there‚ as each biome has its unique features that set it apart. However‚ these unique characteristics may become the source of a biome’s downfall

Lemurs of Madagascar Name: Course: Tutor: Date: Lemurs of Madagascar 1. Madagascar biome is a tropical rain forest. The main characteristic of a tropical rain forest biome is the presence of Warm temperatures throughout the year. In a tropical rain forest biome‚ there are three layers. These layers include the top trees‚ followed by the canopy layer characterized by dens leaves hence low light penetration and the third layer are the ground layer. The ground layer lacks any vegetation owing to

"TEMPERATE GRASSLAND" Temperate grasslands are defined as places where grasses predominate over trees and shrubs. The name for this biome‚ temperate grasslands‚ is a great description for what it is like there. The most important plants in this biome are grasses. Two major kinds of grasslands in the world: • Savannas • Temperate grasslands. Savannas are defined as places where individual shrubs and trees are scattered among the grasses. Temperate grasslands: trees and shrubs are
