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.

The ecosystem concept revolutionized ecology by introducing holistic systems thinking as opposed to individualistic life history studies. Why was this a conceptual breakthrough?
After completing the Gvloer module- Biodiversity: Fragile Ecosystems, why is Evolution controversial anyway? discuss your opinion on the arguments presented. Include relevant information from the chapter, other sources or life experience that have helped shaped your view of how evolution fits with your faith world view.

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

- 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_forward1Which of the following is NOT a consequence of global climate change? coral bleaching more ice at the North and South Poles increases in diseases such as malaria and dengue fever rising sea levels 2How do scientists determine the atmospheric levels of carbon dioxide that existed on Earth hundreds or thousands of years ago? They deduce it from the carbon dioxide content of fossil fuels. They measure it from bubbles of gas trapped in Antarctic ice cores. They estimate it from the numbers of carbon-based life forms that existed over time. They calculate carbon dioxide levels from the temperature records. Scientists do not know the atmospheric levels of carbon dioxide thousands of years ago. 3The two factors that are responsible for the climate of an area are: the number and size of different kinds of species the position of the area in relation to island chains the elevation of the area, and its tree cover the amount of rainfall and temperature. the…arrow_forwardThe Lazy River Environmental Group is a group of fishermen and environmentalists that have worked to assess and clean up the pollution from an old factory on the Lazy River.
