Question

ecology vocabulary (to help you study for thursdays quiz)
directions- at this point, between our activities and notes, you should have a basic understanding of each of the following words. complete the 3 bullets for each of these words. type all answers under each word.
● type what your understanding is about each word (not a copy and paste definition)
● 2 real life examples of each word
● copy and paste a picture that represents each word

1. ecology
2. food chain
3. food web
4. energy pyramid

● what does the arrow represent?
● what does the direction of the arrow mean?
● how much energy transfers from one trophic level to the next?
● where does the remaining energy go, and how is it utilized?

Explanation:

1. Ecology: Ecology is the study of the relationships between living organisms and their environment. Real - life examples: studying how bees interact with flowers in a meadow; observing how fish populations are affected by water pollution in a river. A picture could be of a lush forest with animals in it.
2. Food Chain: A linear sequence of organisms where each is eaten by the next in the chain. Real - life examples: grass → rabbit → fox; algae → shrimp → fish. A picture could be a simple drawing of a plant, a herbivore, and a carnivore in a line.
3. Food Web: A complex network of interconnected food chains in an ecosystem. Real - life examples: in a wetland, multiple food chains involving plants, insects, birds, and small mammals are all linked; in a coral reef, various organisms from plankton to sharks are part of a large food web. A picture could be a diagram showing multiple arrows connecting different organisms.
4. Energy Pyramid: A graphical representation of the flow of energy through different trophic levels in an ecosystem. The arrow represents the transfer of energy from one organism to another. The direction of the arrow means the flow of energy from the organism being eaten to the organism that eats it. Only about 10% of energy transfers from one trophic level to the next. The remaining energy is lost as heat during metabolic processes and is used for the organism's own life - sustaining activities such as respiration, movement, and growth.

Answer:

1. Ecology: My understanding: The study of organism - environment interactions. Examples: Meadow bee - flower interaction; River fish - pollution impact. Picture: Lush forest with animals.
2. Food Chain: My understanding: Linear sequence of who eats whom. Examples: Grass - rabbit - fox; Algae - shrimp - fish. Picture: Plant - herbivore - carnivore drawing.
3. Food Web: My understanding: Interconnected food chains in an ecosystem. Examples: Wetland food web; Coral reef food web. Picture: Diagram of interconnected organisms.
4. Energy Pyramid: Arrow represents energy transfer. Direction means energy flow from eaten to eater. 10% energy transfer between trophic levels. Remaining energy is lost as heat and used for metabolic activities.
