  1. Living organisms, like you, get their energy to move and do work from eating food. Trace the energy transformations that occur from the original radiant solar energy used by plants to mechanical energy in living systems. 130 120 60 70 30 50 40 10 140 8 7 6 5 4 9 3 2 0 180 80 20 160 90 150 170 100 110 1 This screen will disappear in 3 minutes.

  2. Plants convert the radiant solar energy to chemical energy through the process of photosynthesis. The plant is harvested using mechanical energy. The machine that does the harvesting converts chemical energy into mechanical energy. Transportation and processing will also involve the conversion of chemical energy to mechanical energy. When people eat food, their bodies convert the chemical energy stored in food into mechanical energy.

  3. Which diagram best shows the energy transformation from sunlight to chemical energy in an organism? 130 120 60 70 40 50 30 10 140 8 7 6 5 4 9 3 2 0 180 80 20 160 90 150 170 100 110 1 This screen will disappear in 3 minutes. Seconds Remaining.

  4. B – understand that plants are one of the organisms (producers) that make their own food in this process (photosynthesis).

  6. Choice C is the correct answer because it identifies the greatest limitation of this model. • Since food webs are complex, not all organisms can be included in one model. • This diagram also illustrates how the flow of energy is represented by arrows in a food web. The energy from the organism that is consumed flows to the consumer. • For example, the food energy from the deer flows to the mountain lions because mountain lions eat deer.

  7. Define: • Producer • Consumer • Decomposer 130 120 60 70 30 50 40 10 140 8 7 6 5 4 9 3 2 0 180 80 20 160 90 150 170 100 110 1 This screen will disappear in 3 minutes. Seconds Remaining.

  8. Producer – organisms able to use light energy from the Sun to produce food (sugar) from carbon dioxide and water. (Plants) Consumer – organisms that cannot make their own food so they must eat plants and/or other animals Decomposer – organisms such as bacteria and fungi which feed on decaying matter.

  9. Define: • Carnivore • Herbivore • Omnivore 130 120 60 70 30 50 40 10 140 8 7 6 5 4 9 3 2 0 180 80 20 160 90 150 170 100 110 1 This screen will disappear in 3 minutes. Seconds Remaining.

  10. Herbivore – Animals that eat ONLY PLANTS are called herbivores (or primary consumers). • Carnivore – Animals that eat OTHER ANIMALS are called carnivores. • carnivores that eat herbivores are called secondary consumers • carnivores that eat other carnivores are called tertiary consumers • Omnivore - Animals and people who eat BOTH animals and plants

  11. Why there are more herbivores than carnivores? 130 120 60 70 30 50 40 10 140 8 7 6 5 4 9 3 2 0 180 80 20 160 90 150 170 100 110 1 This screen will disappear in 3 minutes. Seconds Remaining.

  12. In a food chain, energy is passed from one link to another. When a herbivore eats, only a fraction of the energy (that it gets from the plant food) becomes new body mass; the rest of the energy is lost as waste or used up by the herbivore to carry out its life processes (e.g., movement, digestion, reproduction). Therefore, when the herbivore is eaten by a carnivore, it passes only a small amount of total energy (that it has received) to the carnivore. Of the energy transferred from the herbivore to the carnivore, some energy will be "wasted" or "used up" by the carnivore. The carnivore then has to eat many herbivores to get enough energy to grow.Because of the large amount of energy that is lost at each link, the amount of energy that is transferred gets lesser and lesser . http://www.vtaide.com/png/foodchains.htm
