The natural world or nature represents the physical world and the living elements found within it. In its broadest sense‚ nature entails all the living and inanimate things that exist within the physical world. All the elements of the natural world‚ whether living or inanimate‚ significantly depend on each other. Of all the living things‚ man crucially depends on the elements of nature for his survival. On the same account‚ we have the responsibility to ensure that the natural world remains intact

one of 12 mega-diversity countries possessing a rich means of all living organisms when biodiversity is viewed as a whole. The greater the multi-diversity of species‚ greater is the contribution to the biodiversity. India’s rich biological diversity - its immense range of ecosystems‚ species and genetic forms is by virtue of its tropical location‚ climate and physical features. India’s fabulous biodiversity is estimated to be over 45‚000 plant species representing about seven percent of the world’s

As habitat fragmentation in southern California split land‚ the integrity of the land changes. Habitat fragments that each has a decrease in area will have an increase in the total perimeter distance collectively (Morrison et al.‚ 2006). This increased area around the habitat exposes more of the internal habitat to the elements‚ reduces the habitat buffer‚ and in turn creates less optimal habitat for species in the fragment (Morrison et al.‚ 2006). This process‚ called edge effect‚ decreases the

Carefully review the Grading Rubric before beginning the assignment. Read "Lab 3: Biodiversity." This lab will allow you to investigate how various organisms alter their environments. Additionally‚ it will allow you to assess the health of ecosystems based upon their biodiversity. Then‚ you will utilize this information and your eScience lab kit to complete Demonstration 1 and Experiment 1 on the Week Three Lab Reporting Form. Make sure to complete all of the following items before submission:

A Balanced Ecosystem - An Aquarium The term ecosystem describes both the living and non-living components of an area that interact with one another. All the components are inter-dependant in some way with each other. An ecosystem may be aquatic or terrestrial. In an aquatic ecosystem rocks are needed for shelter and plants provide oxygen for fish. An ecosystem is balanced when the natural animals and plants and non-living components are in harmony- i.e. there is nothing to disturb the balance.

Forests in Their Age‚ Makeup‚ and Origins A. 2 Major Types of Natural Forests 1. Old-growth/ Primary -uncut/ regenerated forest that has not been seriously disturbed by human activities/ natural disasters for 200 years or more - reservoirs of biodiversity (provide ecological niches for a variety of wildlife species) 2. Second- growth - stand of trees resulting from secondary ecological succession B. Tree Plantation/ Tree Farm/ Commercial Forest -managed forest containing one or two species

plants (Flora) and animals (Fauna)‚ are included when determining biodiversity. On our planet‚ there are 13.6 million species of plants‚ animals and micro-organisms‚ and Australia has about 7% (one million) of these (Australian Museum‚ 2017). Australia has a vast biodiversity because it is classed as a ‘megadiverse country’. Megadiversity is when a country has high levels of biodiversity. One way to measure Australia’s biodiversity is by looking at taxonomic groups. By looking at taxonomic groups

3Q)Describe the harm caused by building roads into previously inaccessible forests. A)Building roads in these once untouched areas of forest result in‚ increased erosion and sediment runoff into waterways‚ habitat fragmentation‚ and loss of biodiversity. Q)Distinguish among selective cutting‚ clear-cutting‚ and strip cutting in the harvesting of trees. A)Selective cutting is when intermediate-aged or mature trees in a forest are cut singly or in small groups. Clear-cutting is when loggers
