*How much energy do they get from the sun?
1. Zooplanktons
2. Small fish
3. Sea urchins
4. Crustaceans
1. Zooplankton: Zooplankton obtain their energy indirectly from the sun through a process called photosynthesis. They consume phytoplankton, which are primary producers that directly convert sunlight into usable energy. Therefore, the amount of energy zooplankton get from the sun depends on the availability and productivity of phytoplankton in their habitat.
2. Small fish: Small fish generally do not directly obtain energy from the sun. They are typically secondary consumers in the food chain, meaning they consume other organisms for energy. These organisms could include zooplankton, larger fish, or other marine organisms. However, the energy they ultimately obtain indirectly from the sun is dependent on the productivity of the lower trophic levels.
3. Sea urchins: Sea urchins are herbivores that mainly graze on algae and other plant-like organisms found in their environment. These algae and plants directly receive energy from the sun through photosynthesis. So, the amount of energy sea urchins get from the sun depends on the availability and abundance of their primary food sources in their habitat.
4. Crustaceans: Crustaceans encompass a diverse group of marine organisms such as crabs, lobsters, shrimp, and krill. Their energy sources vary depending on the species and their feeding habits. Some crustaceans are herbivores, consuming algae and plants, while others are omnivores or even carnivores, preying on other organisms. The energy they derive from the sun is ultimately through the consumption of primary producers or other organisms higher in the food chain, indirectly linking their energy intake to solar energy.
