In any ecosystem, life and energy flows in a pyramid. Trophic levels in rainforests are similar to those in other ecosystems. Organisms known as ​producers​ create energy, and that energy results in a trophic effect through the rainforest food web.…

Covering less than 2 percent of the planet, rainforests are home to more than 50 percent of all plants and animals on the Earth. Rainforests in Central America are warm and wet environments with thick, dense vegetation. These densely-packed plants…

If you’ve never heard that it’s dangerous to go swimming during a lightning storm, consider yourself warned. The water in natural sources, such as lakes and streams, as well that in pools and hot tubs, is an excellent electricity conductor,…

More than 1,000 species of spiders are found in Wisconsin. The state’s native spiders fall well short of the dimensions of the world’s biggest species – certain tarantulas – which may reach 4 inches in length and nearly 10 inches…

The diet of a baby groundhog, also known as a woodchuck, consists of mother’s milk followed by a weaning diet of grasses and vegetables. As the baby grows, additional foods such as fruits, small insects and nuts will be added…

All of physics is concerned with describing how objects move and how certain quantities they possess (e.g., energy, momentum) are exchanged with each other and the environment. Perhaps the most fundamental quantity governing motion is force, which is described by…

The cedar tree is native to the Himalayas and countries around the Mediterranean, but it can be found in many parts of the world with mild climates. True cedar trees have no varieties native to the U.S., but people plant…

The entropy of a chemical system depends on its energy and its multiplicity, or how many different ways its atoms and molecules can be arranged. By adding new arrangements or energy, you increase entropy. A diamond, for example, has low…

The inch is one of the standard units of measurement used in many countries, including the United States. In relation to other non-metric measurements, there are 12 inches in one foot and 36 inches in one yard. In order to…

Soil covers the surface of the planet and can be found in all major environments on Earth. Soil is created by the breakdown of rocks and boulders into smaller and smaller pieces by erosive forces, and the nature of a…
