Ecosystems can change over time in a process known as natural succession.

Unit 1 Discussion Board Deliverable Length: 2-3 paragraphs Details: Ecosystems can change over time in a process known as natural succession. When an ecosystem is disturbed, both the physical (abiotic) and living (biotic) characteristics may be altered. Disturbances may be natural (e.g., a fire started by lightning) or anthropogenic – human caused (e.g., a fire started by a campfire.) Answer the following in your posts: Choose a specific ecosystem and discuss the consequences for damage to the ecosystem and recovery of the ecosystem when it is disturbed by a natural AND an anthropogenic events. Describe the severity of the disturbances. How will the abiotic and biotic characte... click for more

Ranching, its problems, and conservation of environment:

The process of ranching, the adverse effects caused due to ranching on the environment, solutions to reduce the adverse effects of ranching with a discussion regarding the utilization of new technology which renders raching more environmental friendly in nature.

Cellular Respiration and Photosynthesis Co-exist as Paired Metabolic Processes

Part 1: Fill out the following table to compare and contrast Photosynthesis and Aerobic Cellular Respiration. Photosynthesis Aerobic Cellular Respiration Full balanced equation Reactants Products Is this reaction endergonic or exergonic? State which one it is. Energy source used Cell organelles involved in the reaction Role of ATP in the reaction Part 2: After completing the table you will have a basic understanding of these two complementary metabolic processes. Using what you have learned, and additional reference information, answer the following questions. What types of organisms can use Photosynthesis to produce glucose? Provide examples. What typ... click for more

Compare and contrast Photosynthesis and Aerobic Cellular Respiration.

I need the basic difference between these processes.

I need help to create a food web diagram in which I illustrate the energy flow among the organisms of a food chain within a particular ecosystem. Then, determine the interdependency of life of desert biome by examining the organisms found.

In the diagram, include the following items: a. List the different kinds of organisms that can be found in your selected ecosystem. b. Identify the structure and function of the main organs in at least two of the organisms found in your selected ecosystem, and indicate why they are best suited for that environment. c. Label the three major types of organisms that live in your selected ecosystem as follows: “P” for producers, “C” for consumers, and “D for decomposers. d. Name the three types of consumers: herbivores, carnivores, and omnivores within your selected ecosystem. e. List the food chain(s) associated with your selected ecosystem. For each organis... click for more
