UNIT 1 DIVERSITY IN THE LIVING WORLD Chapter 1 The Living World Chapter 2 Biological Classification Chapter 3 Plant Kingdom Chapter 4 Animal Kingdom Biology is the science of life forms and living processes. The living world comprises an amazing diversity of living organisms. Early man could easily perceive the difference between inanimate matter and living organisms. Early man deified some of the inanimate matter (wind‚ sea‚ fire etc.) and some among the animals and plants. A common feature of all

advantage of multiple developmental stages‚ metamorphosis‚ to further diversify occupying many niches and thus increase their chances for survival. All these characteristics contributed to the overriding success of insects as a group: today insect species outnumber those in all other living groups combined (Borror and others 1992). How Do Insects Interact with Humans People benefit from insects in many ways‚ without them‚ human society could not exist in its present form. In contrast‚ many insects

Natural selection occurs in a specific process that results in the formation of new species. This process includes: 1. A species produce more offspring than what can survive 2. In each species

Animal Diversity The number of animal varieties familiar to us is vast as the animal world is diverse. Each distinct variety or type of animals is recognized by scientist as a species. Animals of most species are free-living forms but of others are parasitic in bodies of other animals or even plants. According to their habitats animals are divided into the following types Aquatic animals :- They live in water . Animals living in sea water are called marine & those live in river‚ponds‚streams

The other day‚ you brought up the new anglerfish species. I’m pleased you’ve taken an interest‚ but I don’t think you understand some of the concepts you brought up. So I want to help you understand how evolution works‚ and better understand how creatures like the Lasiognathus dinema evolved. I first want to address Charles Darwin’s concept on evolution. You stated that only the strongest and most important species survive. While strength is an important variable in survival‚ an organism’s fitness
