Output example: Gases return elements to the atmosphere‚ and the water carries materials away.

Topic: Silver is an ancient mineral that dates back since prehistoric times. One thing that makes silver so special is that it was one of the first five metals that we started to use. Silver is found in almost every electronic device there is‚ and as time progresses the usage of it increases‚ unfortunately the amount there is left decreases. How is it created or source of the mineral? (5) Silver is not originated from Earth‚ as it happens it came from space. Many elements were formed in the big

Unit 4 Ecosystems Background Introduction The abundance of a species and species diversity affect how natural resources are processed within an ecosystem. This pattern of processing contributes to functional and compositional characteristics of an ecosystem. But many ecosystems around the world are currently experiencing significant changes in species composition‚ abundance‚ and diversity due to the influence of human activity. These changes have‚ more often than not‚ led to a reduction in species

Use these guidelines to help you with this activity: Herbivores (animals that eat plants) are first level of consumers. Carnivores (animals that eat other animals) are second level of consumers. Green plants transfer the sun’s energy. Parasites feed on other living things. Decomposers break

but they are not the same. We will explore the differences here. A food chain shows a single‚ connected path of energy flow through an ecosystem. Some animals only eat plants while some animals eat other animals. A food chain shows the different levels of eating within an ecosystem. The arrows show the flow of energy from one organism to the next. Most food chains begin with the sun at the bottom. Let’s examine the example on the right. There are three types of organisms in a food chain: producers
