- Using the concepts of trophic levels and energy flow, explain why the ecological footprint of a vegetarian person is smaller than that of a meat-eaterA black bear normally eats many different types of food. When the black bear eats berries, what trophic level is the bear?Availability of energy is less for entities at higher trophic levels.Why?
- Think about the amount of energy at each trophic level. Would you expect to see a food chain with 10 levels in a normal ecosystem?Explain why there are differences in the efficiency of energy transfer between trophic levels. Explain what happens to the energy which is not transferred to the next trophic level in a food chain when one organism feeds on another.Name the trophic levels in an ecosystem and explain how energy moves through the trophic levels. Can you use the words food chain and food web in the discussion.
- A class is studying the tropic levels of an ecosystem. The pyramid of biomass shown is a model of these trophic levels. Which of the following is the best explanation of the available energy at each of the trophic levels in this ecosystem ? ANSWER CHOICES ARE IN THE PHOTO. thanks.can someone please help me to answer questions a-b thank you 1In a trophic pyramid, each level is smaller than the one below. a) What does the size of each level represent? b) How much energy is transferred from level to level? c) Explain why the levels get smaller as the trophic pyramid goes up.In a Central Texas grassland, the producers incorporate 12,000 kJ of energy from the sun into their tissues. About how much energy would be incorporated into the tissues of herbivores?
- Use the information and diagram to answer the following question. The energy pyramid is a shape often used to describe and identify roles of organisms in an ecosystem. image Using the sections of the pyramid provided, which answer choice describes a relationship found in an ecosystem? A. II represents secondary consumer and III represents a tertiary consumer, which explains why the top of the pyramid is smaller than the base. B. IV represents producers and I represents primary consumers which explains why the base of the pyramid is the largest. C. IV represents the top predator and I represents the primary producers, which explains why the base of the pyramid is larger than the top. D. I represents a predator and II represents a prey which explains why the top of the pyramid is smaller than the base.Using organisms that live in San Diego County, draw your own food CHAIN here.
