Summary Introduction
To determine:
Whether ecosystems are capable of evolving or not. If capable, then it will be a form of Darwinian evolution or not.
Introduction:
Evolution is known as changes in the heritable characteristic of a population over a period of time and over several generations. Ecosystem, comprises of, biological populations, whether plants or animals, the non living surroundings of these populations.
The interaction of biological and non-biological constituents takes place in an ecosystem which, leads to gradual change in the attributes of the biological populations.

- Two terrestrial ecosystems based on photosynthesis and chemolithosynthesis (hydrothermal vents) trap their energy from specific energy sources. Tidal squeezing has also been suggested. The type of energy sources define the character of the ecosystems observed. What other energy source can you identify that might drive other kinds of ecosystems elsewhere in the universe? Speculate on the type of organisms that might evolve based on that energy source.What would be the characteristics of the primary producers (the organisms that trap the energy)?arrow_forwardThe ecosystem concept revolutionized ecology by introducing holistic systems thinking as opposed to individualistic life history studies.

The carrying capacity of an ecosystem is the maximum number of organisms that an area can support over time. The density of a population may cause huge changes in the environment so that the environment becomes unstable for the survival of that species. Humans can mess up natural selection and have either a positive or negative effect. OBJECTIVES Graph data on the Kaibab deer population of Arizona from 1905-1939. Analyze the factors that caused the changes in the deer population. PROCEDURE: Before 1905, there was an estimated 4000 deer on almost 30,000 hectacres of land on the Kaibab Plateau in Arizona. The average carrying capacity of the land at that time was estimated to be about 30,000 deer. Being concerned about the low number of deer, President Theodore Roosevelt created the Grand Canyon…arrow_forward

You are discussing the choice of the "oil-eating" bacteria that you will use to clean the affected area from the oil spill and your team wants to know whether the Kalba sea constitutes a natural habitat for these bacteria. Formulate a hypothesis stating why or why not the Kalba sea area can be considered a natural habitat for such bacteria. Support your answer by discussing the role of evolution in contributing to the survival and thriving of “oil-eating" bacteria. Explain how and why these bacteria acquired these characteristics.arrow_forward
