Genetic diversity is all the different genes contained in all the living species, including individual plants, animals, fungi, and microorganisms. Biodiversity is a compound word. 0000468459 00000 n Only 250,000 species of the total stock are plants. The area can be large or small. No feature of Earth is more complex, dynamic, and varied than the layer of living organisms that occupy its surfaces and its seas, and no feature is experiencing more dramatic change at the hands of humans than this extraordinary, singularly unique feature of Earth. 0000010985 00000 n 0000008073 00000 n Biodiversity can be subdivided into three levels as follows: At finer levels of organisation, biodiversity includes the genetic variation within species, both among geographically separated populations and among individuals within the single population. 0000002530 00000 n 0000440111 00000 n Species Diversity. �L�x�ߏݟ����G�WMo�����������,�������L��� ����m�#�X�DJbvbY� ����{BP�'Lf1�l\�Ɲց����D y�u��f���K\�#��=K��P!+���,?��ǤZgX��6Jg�U3��[0PV�]��/B�G�}ћ|� �0o��(��.�~r�����4L#P`��xKح/gC�J�9��P�"x�o������Kx endstream endobj 226 0 obj 263 endobj 122 0 obj << /Type /Page /Parent 108 0 R /Resources 123 0 R /Contents [ 135 0 R 137 0 R 143 0 R 145 0 R 147 0 R 149 0 R 151 0 R 160 0 R ] /MediaBox [ 0 0 1224 792 ] /CropBox [ 0 0 1224 792 ] /Rotate 0 >> endobj 123 0 obj << /ProcSet [ /PDF /Text ] /Font << /F1 129 0 R /F2 130 0 R /F3 127 0 R /F4 134 0 R /F5 139 0 R /TT1 142 0 R >> /XObject << /Fm2 168 0 R /Fm4 176 0 R /Fm6 184 0 R /Fm8 192 0 R /Fm10 200 0 R /Fm12 208 0 R /Fm14 216 0 R /Fm16 224 0 R >> /ExtGState << /GS1 159 0 R /GS2 155 0 R >> /ColorSpace << /DefaultCMYK 125 0 R /Cs8 125 0 R /Cs9 126 0 R >> >> endobj 124 0 obj << /Type /FontDescriptor /Ascent 718 /CapHeight 718 /Descent -207 /Flags 32 /FontBBox [ -166 -225 1000 931 ] /FontName /Helvetica /ItalicAngle 0 /StemV 88 /XHeight 523 /StemH 88 >> endobj 125 0 obj [ /ICCBased 157 0 R ] endobj 126 0 obj [ /Separation /All 125 0 R 158 0 R ] endobj 127 0 obj << /Type /Font /Subtype /Type1 /FirstChar 32 /LastChar 183 /Widths [ 278 278 355 556 556 889 667 191 333 333 389 584 278 333 278 278 556 556 556 556 556 556 556 556 556 556 278 278 584 584 584 556 1015 667 667 722 722 667 611 778 722 278 500 667 556 833 722 778 667 778 722 667 611 722 667 944 667 667 611 278 278 278 469 556 333 556 556 500 556 556 278 556 556 222 222 500 222 833 556 556 556 556 333 500 278 556 500 722 500 500 500 334 260 334 584 350 0 350 222 556 333 1000 556 556 333 1000 667 333 1000 350 611 350 350 222 222 333 333 350 556 1000 333 1000 500 333 944 350 500 667 278 333 556 556 556 556 260 556 333 737 370 556 584 333 737 333 400 584 333 333 333 556 537 278 ] /Encoding /WinAnsiEncoding /BaseFont /Helvetica /FontDescriptor 124 0 R >> endobj 128 0 obj << /Type /FontDescriptor /Ascent 718 /CapHeight 718 /Descent -207 /Flags 262176 /FontBBox [ -170 -228 1003 962 ] /FontName /Helvetica-Bold /ItalicAngle 0 /StemV 140 /XHeight 532 /StemH 140 >> endobj 129 0 obj << /Type /Font /Subtype /Type1 /FirstChar 32 /LastChar 149 /Widths [ 278 333 474 556 556 889 722 238 333 333 389 584 278 333 278 278 556 556 556 556 556 556 556 556 556 556 333 333 584 584 584 611 975 722 722 722 722 667 611 778 722 278 556 722 611 833 722 778 667 778 722 667 611 722 667 944 667 667 611 333 278 333 584 556 333 556 611 556 611 556 333 611 611 278 278 556 278 889 611 611 611 611 389 556 333 611 556 778 556 556 500 389 280 389 584 350 0 350 278 556 500 1000 556 556 333 1000 667 333 1000 350 611 350 350 278 278 500 500 350 ] /Encoding /WinAnsiEncoding /BaseFont /Helvetica-Bold /FontDescriptor 128 0 R >> endobj 130 0 obj << /Type /Font /Subtype /Type1 /FirstChar 66 /LastChar 121 /Widths [ 722 722 722 667 611 778 722 278 556 722 611 833 722 778 667 778 722 667 611 722 667 944 667 667 611 333 278 333 584 556 333 556 611 556 611 556 333 611 611 278 278 556 278 889 611 611 611 611 389 556 333 611 556 778 556 556 ] /Encoding /WinAnsiEncoding /BaseFont /Helvetica-BoldOblique /FontDescriptor 131 0 R >> endobj 131 0 obj << /Type /FontDescriptor /Ascent 718 /CapHeight 718 /Descent -207 /Flags 262240 /FontBBox [ -174 -228 1114 962 ] /FontName /Helvetica-BoldOblique /ItalicAngle -12 /StemV 140 /XHeight 532 /StemH 140 >> endobj 132 0 obj 817 endobj 133 0 obj << /Type /FontDescriptor /Ascent 718 /CapHeight 718 /Descent -207 /Flags 96 /FontBBox [ -170 -225 1116 931 ] /FontName /Helvetica-Oblique /ItalicAngle -12 /StemV 88 /XHeight 523 /StemH 88 >> endobj 134 0 obj << /Type /Font /Subtype /Type1 /FirstChar 32 /LastChar 121 /Widths [ 278 278 355 556 556 889 667 191 333 333 389 584 278 333 278 278 556 556 556 556 556 556 556 556 556 556 278 278 584 584 584 556 1015 667 667 722 722 667 611 778 722 278 500 667 556 833 722 778 667 778 722 667 611 722 667 944 667 667 611 278 278 278 469 556 333 556 556 500 556 556 278 556 556 222 222 500 222 833 556 556 556 556 333 500 278 556 500 722 500 500 ] /Encoding /WinAnsiEncoding /BaseFont /Helvetica-Oblique /FontDescriptor 133 0 R >> endobj 135 0 obj << /Filter /FlateDecode /Length 132 0 R >> stream Three different levels, of biodiversity it measured on the other hand, nature always tries to in!
