[Energy resources]: The 2 broad types Pros and Cons of each type Ways in which they are harnessed There two main types of energy these are: 1. Potential energy 2. Kinetic energy Potential energy Potential energy is energy stored due to position. The following are some example in which potential energy can be found. 1. Wound-up spring When a spring of a dock work toy car unwinds‚ the stored energy in the spring drives the wheels and the car moves. The wound-up spring is said to posse potential

ECOSYSTEMS AT RISK – CASE STUDY 2 PART 1: CORAL REEFS – OVERVIEW Coral reefs are often referred to as “the rainforests of the sea” because of they form some of the most diverse ecosystems on Earth. Its massive structure is formed from coral polyps (tiny animals that live in colonies) that support approximately 25% of all known marine species by providing essential habitats. Factors affecting reef development and survival include temperature‚ light‚ sedimentation and salinity of the water. Without

Aquatic ecosystem An estuary mouth and coastal waters‚ part of an aquatic ecosystem. An aquatic ecosystem is an ecosystem located in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. What is an aquatic ecosystem? Aquatic systems are those that contain plants and animals that predominantly depend on a significant amount of water

The oceans cover approximately 70 percent of the surface of the earth and have a cyclical effect on weather‚ e.g. temperature‚ precipitation and air quality. Regardless of your views on global warming‚ the fact remains that humans have an impact on the marine ecosystems through waste from chemicals and debris polluting this vast renewable resource. Based upon current scientific evidence‚ emissions of greenhouse gases from human activities

Introduction Ecosystem is similar to a community. It consists of species‚ living organisms and the abiotic factors‚ their habitat. Living organisms includes animals‚ plants‚ insects‚ micro-organisms. For their habitat‚ they are the non-living nature which are soil‚ sunlight‚ water‚ precipitation. There are two types of ecosystem. Terrestrial ecosystem which is on the land and aquatic ecosystem which is under the water. Over-breeding is the increase of offspring of a species to a excessive number

An 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
