Ecology Essay African lions play a big role in the ecosystem. They are at the top of the food chain and are responsible for 85% of predation in their habitat. They prey on herbivores such as buffalo‚ antelope and zebras. The African lion’s biome is in the tropical grassland and their habitat is the grassy plains of the African savanna. Without the lion‚ the ecosystem would be unbalanced and unstable. The African lion‚ being at the top of the food chain‚ interacts with other organisms in many

Ecosystem is a community of living organisms (plants‚ animals and microbes) in conjunction with the nonliving components of their environment (things like air‚ water and mineral soil)‚ interacting as a system. These components are regarded as linked together through nutrient cycles and energy flows. As ecosystems are defined by the network of interactions among organisms‚ and between organisms and their environment‚ they can come in any size but usually encompass specific‚ limited spaces (although

Intercations Biological interactions are the effects organisms in a community have on one another. In the natural world no organism exists in absolute isolation‚ and thus every organism must interact with the environment and other organisms. An organism’s interactions with its environment are fundamental to the survival of that organism and the functioning of the ecosystem as a whole. In ecology‚ biological interactions can involve individuals of the same species (intraspecific interactions) or individuals
