Woodlands have more biodiversity than any other habitat in Britain. Trees are home to a huge number of other plants‚ insects‚ fungi‚ mosses‚ litchins‚ birds and small animals‚ which all provide food for other animals higher up the food chain. Protecting our woods is a great way to protect wildlife. So why do we encourage people to chop down trees and burn them? And how can a Scout groups and two abseilers help?

interesting investigation into the effects of different chemical concentrations on a metabolic process and whether or not an increase of caffeine would increase the rate of metabolism in multi-celled organisms. These daphnia have been kept in a freshwater habitat at room temperature beforehand. Hypothesis It is predicted that a higher concentration of caffeine the daphnia are subjected to will increase the heart rate more than compared to a solution of a lower caffeine concentration. The change

There are different types of license’s: there is freshwater‚ saltwater‚ crab and lobster license’s.If one is just helping out on the boat like baiting hooks‚ taking of the fish or tying lines that person is required to have a license.

Aquatic environments are classified as ocean waters and inland waters (groundwater and surface water). Ocean waters contain approximately 35 ppt salt; freshwaters which include lakes‚ ponds‚ groundwater‚ river and spring‚ has 0.05 ppt salinity. Special habitats in hydrosphere include bottom sediments‚ biological and non-biological surface‚ and interface (between atmosphere and hydrosphere or lithosphere and

Economic studies estimate the population of Texas to increase at an average of 1.7 percent annually. The growth supports the demand for retail trade‚ services‚ and government output (Rylander‚ 2002). However‚ increased water use is a result of the growth as well. West Texas’ primary sources of water are aquifers‚ such as the Ogallala Aquifer (Wheeler‚ 2008). They are key components for the economic development‚ growth‚ and survival of the agriculture‚ ranching‚ energy‚ and industrial as well

The water came from outer space to Earth. The water was brought to the planet for the comets. The water has a different structure for each state (gas‚ liquid‚ ice). Liquid water has random molecules. On the other hand‚ the ice has a more stable structure. The different structure between ice and liquid water can explain why the ice has less density than liquid water. Temperature is responsible for increasing the dissolution of components‚ and electrical conductivity. Pure water is not a good conductor

Water is the foundation of life. And still today‚ all around the world‚ far too many people spend their entire day searching for it.Water covers 70% of our planet‚ and it is easy to think that it will always be plentiful. However‚ freshwater—the stuff we drink‚ bathe in‚ irrigate our farm fields with—is incredibly rare. Only 3% of the world’s water is fresh water‚ and two-thirds of that is tucked away in frozen glaciers or otherwise unavailable for our use. Waterscarcity can be defined as a condition

Increased salinity would occur from rising saltwater into the Everglades from the Florida Bay. The increase in salinity would damage freshwater ecosystems.

Fish cold-blooded‚ limbless‚ completely aquatic vertebrates‚ having gills‚ commonly fins‚ and typically elongated torpedo-shaped body mostly covered with scales. Fish are usually grouped into four classes‚ three living (Agnatha‚ Chondrichthyes‚ and Osteichthyes) and one extinct (Placodermi): 1. Agnatha‚ the primitive jawless fishes‚ including the cyclostomes (lampreys and hagfishes) and extinct armoured fishes known as ostracoderms‚ none of which has gill arches (bony frames for the gills);
