Question

in an ecological pyramid, which type of organism always has the least amount of energy available?
producers
herbivores
carnivores
apex predator
where does cellular respiration take place? *
in the nucleus
in the mitochondrion
in the chloroplast
in the roots

Explanation:

• For the first question: In an ecological pyramid, energy decreases as we move up trophic levels. Apex predators are at the top, so they have the least energy. Producers (like plants) have the most as they convert sunlight. Herbivores (plant - eaters) get energy from producers, and carnivores from herbivores. But apex predators are at the highest trophic level.
• For the second question: Cellular respiration is the process of breaking down glucose to release energy. Mitochondria are known as the "powerhouses" of the cell. The nucleus contains DNA, chloroplasts are for photosynthesis (in plants), and roots are plant organs (not the site of cellular respiration for the whole concept).

Answer:

• First question: Apex Predator
• Second question: In the mitochondrion
