Each organism has its role to play in the environment to keep the cycle of life regulated in a biosphere. The environment an organism lives in includes all external factors, such as abiotic and biotic factors, and is constantly changing. This continuous process demands the efforts of scientists and biologist to study and document the actions of each organism. The study of organisms and their interactions with their environment is termed ecology. Ecology is a broad science and includes some of these examples: Population processes, including reproduction, death, migrations, and death; interspecific interactions such as competition, predation, mutualism, and parasitism; structures of animal and plant communities, and the flow of energy and nutrients through an ecosystem.
Unit 6 Seminar 1.How are these cycles essential for life and what roles do these forms of matter serve for different types of organisms? Ecology is the branch of science that studies interdependent groups of living things, called ecosystems. Each ecosystem is characterized by its physical environment and its community of living organisms. In every ecosystem many different organisms, each competing for matter and energy, occupy their own ecological niches. Photosynthetic plants in the first trophic level use energy from the Sun; these plants provide the energy for animals in higher trophic levels.
Living organisms and the physical environment have a close relationship. They interact with each other. The biosphere is the parts of Earth inhabited by living organisms. The biosphere consists of specific geographical areas known as biomes. A biome is a collection of different types of ecosystems.
Development reflects the influences of several environmental systems, and these systems are the micro system, the mesosystem, exosystem and the macro system (Oswalt, 2008). The micro system is the setting where the individual resides, which consists of family, peers, schools and the neighborhood. It is
What are the three tropic categories? Producer which includes plants, trees, vegetables and fruit. Consumers which are any organism that can’t make its own food. Decomposer an organism that primarily feeds on dead organisms or the waste from living organisms. Give 2 examples of each trophic categories that can be found in your town, city, or county.

What is the main question asked on p.27 aimed at focusing the reader’s thinking and learning? * How do organisms in ecosystems use one another as food? * How are organisms linked in their feeding relationships? * Does the availability of food in an ecosystem affect the survival of
Reservoirs can be a person, an animal, or an environmental component, such as soil or water. 3. The Portal of Exit. This link is needed for the pathogen to leave the reservoir. If the reservoir is a human, then the portal of exit may be saliva, mucous membranes, feces, blood, or nose or throat discharges.
Females lay about 300 to 400 eggs per cocoon, and about four cocoon's every summer. The black widow spider is nocturnal, it hunts and moves about at night. It is a very dangerous spider. In fact its venom is 15 times more dangerous than that of a rattlesnake. It is an invertebrate animal belonging to the arachnid family, to the class of the arthropods.
