Explain The Two Basic Components Of Ecosystem
1. What are the two basic components of any ecosystem?
• Abiotic – nonliving environment
• Biotic – living components
SOURCE: Instructional Material
2. What two physical factors determine the type of biome that is present in an area?
• Climate
• Geography
3. Explain why autotrophs are called producers and heterotrophs are called consumers.
• Autotrophs are called producers because they make their own food
• Heterotrophs are called consumers because they rely on other organisms for their energy and food supply
4. Select the correct answer from the terms in the parentheses. Ecosystems will recycle nutrients, but ecosystems will not recycle energy.
5. Define trophic level.
• Trophic level – composed of all organisms that feed at a particular

6. This question is based on the following description of an ecosystem: Organism A is a plant that performs photosynthesis. Organisms B eats Organism A; Organism C eats Organism B and Organism D eats Organism C. This is summarized in the following diagram: A B C D. The direction of the arrows indicated the organism that eats the other.
Based on this example fill in the blanks with the appropriate answer.
Organism _A__ is a producer; Organism C belongs to trophic level __3__.
7. If an herbivore consumes 200 pounds of plant material, roughly how much is converted to herbivore use?
• 20 lbs
8. When considering ecosystems, explain the basic difference between reservoirs and exchange pools.
• Reservoirs – fossil fuels, minerals in rocks, and sediments in oceans contain inorganic nutrients that are limited in availability
• Exchange pools – atmosphere, soil, and water are ready sources of inorganic nutrients
SOURCE: Instructional Material
9. Identify two reservoirs for carbon.

What are the three age groups of population that are depicted in age structure diagrams? Which one has the greatest impact on increased population growth in LDCs?
• Pre-reproductive
• Reproductive
• Post-reproductive
• Pre-reproductive has the greatest impact on increased population growth in LDCs
23. Identify and define the types of renewable energy.
• Renewable energy – energy from sources that are constantly being formed and still may affect the environment
• There are 6 types of renewable energy : solar, wind, biomass, hypo-electric, geothermal, and alternative
24. What is the danger presented by chloroflurocarbons?
• Breaking the ozone shield
25. What is biodiversity and what contributes to its loss?
• Biodiversity – the variability among living organisms from all sources, including marine, terrestrial, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species, and of ecosystems.
• Those that contribute to its loss are disease, exploitations, pollutions, habitat loss, and alien species

Plankton Activity Postlab, Questions And Answers
989 Words | 4 PagesPlankton Activity Postlab 1) Apply 2.5: Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales. Explain how the abundance of phytoplankton in the pond depends on the abundance of an abiotic resource such as nitrogen. - Phytoplankton are the producers in the pond. Species of organisms in ecosystems have their own carrying capacity relative to other species, and carrying capacities are determined by particular abiotic and biotic resources in an ecosystem. An increase in nitrogen levels in the pond (e.g. from fertilizers) will result in a dramatic increase in phytoplankton levels, but once phytoplankton population reaches its carrying capacity (determined by availability of other resources besides nitrogen, [DO] levels, predation etc.),
The Sixth Extinction
1097 Words | 5 PagesEvaluating The Sixth Extinction’s Conclusion Throughout The Sixth Extinction, author Elizabeth Kolbert explains how several different natural species have gone extinct or seen their populations dwindle. Each section is unique: no species dies the same way. Kolbert elaborates how extinction has never been uniformitarian or catastrophist but rather a combination of the two. Consequently, the last chapter effectively demonstrates the tragedy of an anthropogenic based extinction but fails to express any urgency or necessity in conjunction with prior sections.

Trophic Energy Lab Report
738 Words | 3 Pages1 Ecosystem Dynamics and Trophic Energy Marc Mueseler BIO111 Biology Laboratory Abstract: The purpose of this experiment is to study different ecosystems and observe the change in the number of organisms at each trophic level as well as the energy transfer to each of these levels. It was observed that the number of organisms dropped off significantly from level to level as the energy transfer efficiency was approximately 10% at each heterotrophic level. Each ecosystem was only able to support about four levels before all of the energy in the system was essentially depleted. The number of organisms in each ecosystem was dependent upon the number of producers available to make their own energy thereby making that energy available to

After the producers were all grouped together, we were left with the consumers. A primary consumer solely eats the producers making them herbivores. Secondary consumers are omnivores, meaning they eat

Disadvantages Of Mutualism
1158 Words | 5 PagesOrganisms require the interaction with other biotic and abiotic factors for a harmonious existence in this nature and is crucial to its existence as well as the functioning of the whole ecosystem (Elton 1968).Depending upon the strength, duration, direction of their effects and mechanism of the interaction,these interactions can be further classified and it spans from species interacting only once in their lifetime (e.g. pollination) to those which completes their entire life in another (e.g. endosymbiosis). The interactions may be detrimental as consumption of the other as in the case of predation, herbivory, or cannibalism or may be advantageous to both as in mutualism. It is not mandatory that the effects of interactions are always direct. It can be also incidental through mediaries such as shared resources or common enemies. Positive and negative interactions are the two types of interactions based on whether the interactions are beneficial or harmful to at least one of the interacting partners .
Deforestation Effects
871 Words | 4 PagesWhen animals lose their habitat (Anadiplosis), they are not accustomed to their new surroundings and could potentially go extinct. Species depend on forests to survive and when the forests are cut down, the animals have nothing left. Forests are heavily depended on for resources and ways of life. The Pachamama Alliance Organization claims that, “the tropical rainforests of South America are responsible for 20% of earth’s oxygen.” This proves the earth relies greatly on forests and may suffer consequences because of the speedy rate trees are being cut
