• tertiary consumers-a carnivore that eats secondary consumers • trophic levels-levels in yhe feeding structure of organisms. Higher trophic levels consume organisms from lower trophic levels • food chain- The sequence of consumption from producers through tertiary consumers. • food web- A complex model of energy and matter move between trophic levels. • Scavengers-a carnivore that consumes dead animals • Detritivores- an organism that specializes in breaking down dead tissues

The organisms in every ecosystem can be assigned to trophic categories. What are these categories‚ and how do they function together in food webs to make sustainable systems? Organisms in ecosystem An ecosystem is an unrestricted of organisms interrelating with respectively other and with their environment like energy is switched‚ such as the cycling of fundamentals‚ emerge. The organism’s ecosystem is a fundamental perception in Biology and Ecology‚ helping as the level of biological association

As shown by the title‚ our earth’s biodiversity is at crisis. But some may wonder‚ what is biodiversity? Wikipedia tells us that biodiversity is the variation of life forms within a given ecosystem‚ biome‚ or on the entire Earth. Interesting enough‚ my science teacher was starting on the Biodiversity chapter when I spotted this poster. We learnt about the classification of species using their common characteristics‚ but I realize that there are always exceptions. For instance‚ we know that mammals

Surviving on a Desert Island Sometimes when I am daydreaming‚ I think about far off places‚ such as the beautiful uninhabited islands in the South Pacific. I imagine myself being shipwrecked on one of these islands‚ the way actor Tom Hanks was in Castaway. Probably I’ll never be stranded on a desert island‚ but if I were‚ I would like to have three things with me: Machete‚ Fishing Line‚ and A lighter The first thing that I would like to have is a machete. A machete will help cut

ECOLOGICAL PYRAMIDS ECOLOGICAL PYRAMIDS • If we arrange the organisms in a food chain according to their trophic levels‚ we often form a pyramid with a broad base representing primary produces & only a few individuals in the higher trophic level. • This pyramid arrangement is especially true if we look at the E content of an ecosystem. • Following the 2nd law of thermodynamics‚ less food E is available to the top trophic level than is available to the preceding level. • For example‚ it takes
