|
What is Regular distribution? |
Regular Distribution; very rare in nature, clear pattern, uniform, possible terrestrial species : : : : : : : : : : : : : : : : : : : :
|
|
|
What is Random Distribution? |
Random Distribution; no clear pattern exists, random distribution of resources . . . . . . . . . : :: .. ' . |
|
|
What is Clumped Distribution? |
Clumped Distribution; possibly the most common pattern reflecting the fact that the species need resources that are not distributed uniformly, patch distribution of resources ::: ... ::: "" ... '''' ::: .,., |
|
|
What is a plan Sketch? |
- arial or surface view of a representative area within an ecosystem, it shows to scale the distribution of organisms in a measured and plotted view
|
|
|
What is a profile sketch? |
- a side-on view of an area showing to scale the distribution of organisms along a line |
|
|
What is the estimating of abundance equation for plants? |
Average % = total % no. of quadrats |
|
|
What is the estimating of abundance equation for animals? |
Capture - Recapture Method Abundance = number captured x number recapture number marked in recapture
first sample of captured birds, weeks later birds get captured again to find if any marked in previous capture is caught again |
|
|
What are some animal sampling techniques? |
- beating tray - sweep net - Tullgren funnel - pitfall trap - kick sampling - Longworth small mammal trap - counting from plane - transmitters or tags |

|
What is Photosynthesis? |
Process where they convert Carbon Dioxide and Water to Glucose and Oxygen. |
|
|
Term; Producers |
Plants that make their own food rather than eat or consume other organisms |
|
|
Term; Consumers |
plants/animals that eat or consume other organisms |
|
|
Identify (name) uses of energy by organisms? |
Organisms use the sun as and energy source to undergo the process of Photosynthesis, where they convert Carbon Dioxide and Water to Glucose and Oxygen. All organisms release energy as heat during the process of Respiration. |
|
|
Describe the roles of photosynthesis in ecosystems? |
Photosynthesis is the process in which plants use the energy from sunlight to convert carbon dioxide and water into glucose(C6H12O6) and oxygen. Plants use photosynthesis in |
