Definition of Open Education Resource (OER) Open Education Resources (OERs) are resources such as tutorials, documents, videos, live streaming videos, lecture notes, tests, assignments, quizzes and activities. OERs assist teachers in providing interesting and innovative lessons to students of all grades. It also provides education to students of all ages and all sectors. The key point of OERs is that they are in the global public domain and anyone can access them free. (JISC. Lou McGill, 2014). OERs

Ecology Culminating Task Food Pyramids: Food Pyramids are pyramid graphs showing the different levels of population, food energy, and other factors. Some of these pyramids include the Pyramid of Biomass which shows the total amount of dry mass per trophic level. The trophic level of an organism is the position it occupies in a food chain. The other pyramids are Pyramid of Numbers, which show how many of the creature per trophic level and Pyramid of Energy which shows how much total energy is available

Biotic Pertaining to living organisms. Carrying capacity A maximum number of individuals or maximum population density that a habitat can support. Community All the organisms that live within a given area. Consumer An organism that obtains food from other living organisms. Ecological succession Changes in the species composition of an ecosystem following a disturbance. Ecology The study of how organisms interact with their environments. Ecosystem All the organisms that live within

Based on the background and research, an overview of a solution to the problem and an implementation process to be executed by Tom Rutherford, HR director of Food Chain Supermarkets, Inc. can help with the discrimination issue(s) presented in the case.   Summary of Case Human resource director of Food Chain Supermarkets, Inc., Thomas L. Rutherford was disturbed by a conversation he had with Walter Jackson, an employee

that resist degradation and continue to persist in the environment. Such chemicals pose a threat to humans, biodiversity and the environment due to their ability to bio-accumulate in organisms as well as biologically magnify through levels of the food chain (UNIDO, n.d.). POPs are also classified as long-range transport pollutants as they are able to travel far distances from the source of contamination by natural means such as water, wind and atmospheric cycles. For this reason, such pollutants are

that every organism that is part of that particular environment is a part of a food chain, or a chain of transfer of energy from one organism to another. To enable us to better keep track of what an organism role is in an environment, organisms are put into trophic levels in a way that organizes them based on their role in an ecosystem. A trophic level is a group of organisms that are on the same level of the food chain and therefore share in some distinctive characteristics. The first, or bottom

The contribution of cockroaches in the ecosystem. What will happen if there were no cockroaches? Cockroaches are one of the ancient species, it begins to be found from the Carboniferous period, about 320 million years ago [1]. It belongs to the group of Blattodea, undering the category of Inseacta. Most of us has seen cockroaches, we often see them hiding inside the dark and humid place in our home, including the kitchen, toilet or the gutter. Every time we see them, we would never be nice to them

Fish, one of the worlds’ leading food source in all regions of the world, but what if one day that food source was to deplete so drastically that one could no longer use it as a food source? What would happen to the people that rely solely on this source? What would happen to the people that relied on catching fish as a job? What would happen to the worlds’ economy? These are only a few questions that should be a concern in the result of Overfishing. The ocean is a big and mass world living among

fourth trophic level of the food web. In relation to the bioaccumulation factors of metals along trophic levels, Zn shows the most consistent trend in both regions (Table 3.3). Although the higher bioaccumulation factors for all metals were noted for primary consumers at the second trophic level, bioaccumulation factors for Pb in El-Manzala (3.7) and in Al-Tebbin (1.4) were higher at the third and fourth trophic levels, respectively. Lead of the two investigated food webs had the highest frequency
