covered regarding the topic of food webs in your one to two paragraph explanation. "All the life of the planet is inter-related... each species has its own ties to others‚ and ...all are related to the earth." I think the quote means that there are so many ecosystems on Earth and they are all tied together. All species on Earth are part of a food change and each one has a tie to another species and they all contribute and relate to the Earth. There are food chains in every part of the Earth.

Grass-mouse-snake-hawk 2. In an ecological pyramid‚ what happens to energy‚ biomass and # of species as you move up? Why? They all decrease because energy is lost as it moves up each trophic level. Each trophic level requires more energy to sustain it‚ increasing competition for resources and causing number of

of nature consisting of community of organisms‚ interacting with each other and with their surrounding physical and chemical environment. In order to be an ecosystem‚ energy should be transferred in a form of organisms. There should be a food chain in order to be an ecosystem‚ when one organism eats the other. SOME IMPORTANT ECOLOGICAL TERMS 5.1.1 Population: All living things of the same species in a habitat at any one time. Ex. Panda population in China in 1989 Community: All the

This chapter covers Ecology and‚ as such‚ has a vocabulary all its own – which is often examined. Environment: All the organisms (biotic) and the conditions (abiotic) which exist in an area Abiotic factors: all the non-living factors in an environment‚ such as rainfall‚ temperature‚ soil. Biotic factors: All the living organisms in an area – such as producers‚ predators and parasites. Population: All the members of one species living in an area Community: The total of all the populations living in

everyday struggle between the omnivore and its food choices. The omnivore’s dilemma comes about every time the omnivore becomes hungry. There is the question of “What do I want to eat?” for each meal. Pollan believes that the omnivore has three main food chains: the industrial (corn)‚ the pastoral (grass)‚ and the personal (forest). I chose Part III Personal of The Omnivore’s Dilemma. The personal food chain is where the hunter-gatherer finds their food within the forest. I will be reviewing chapters
