Based on the food chain provided below.
Which model best represents the energy available at each trophic level in the food chain?

Which organisms' populations are most likely to decrease if deforestation significantly reduces the bird population?
Which tables correctly classify the organisms in the following food web?
A large portion of coral reefs has been damaged due to ocean warming and pollution. This destruction has led to habitat loss for many marine species, including clownfish, sea turtles, and reef sharks. Additionally, the decline in coral reefs has reduced their ability to protect coastlines from erosion.
Which of the following is the most likely consequence of this environmental change?
What is one impact on the food web if the wild cat were removed?
Due to wildfires there has been a significant reduction of green plant available.
How can wildfires affect the rest of the food web?
Cane toads (Rhinella marina) are an invasive species introduced to Australia in the 1930s to control agricultural pests. However, they spread rapidly and negatively impacted native ecosystems. To control the cane toad population, biologists introduced several species of predatory snakes known to consume amphibians.
Which of the following is a potential unintended negative consequence of releasing these three snake species into the environment?
Axolotls are critically endangered amphibians native to Mexico's freshwater lakes, particularly Lake Xochimilco. These unique salamanders rely on clean, stable aquatic environments for survival. However, human activities have significantly reduced their populations.
Which human activity would most likely decrease the ability of Axolotls to survive?
Many ocean ecosystems rely on large predatory fish, such as sharks and tuna, to regulate prey populations. However, due to overfishing, their populations have drastically declined. This disruption has had cascading effects on marine food webs.
Which consequence is most likely to occur due to the overfishing of large predatory fish?
A group of scientists studying African savannah ecosystems has observed that prolonged droughts have led to a decline in grass and vegetation. This decline has reduced food availability for herbivores such as zebras and gazelles, causing their populations to decrease.
How is this environmental change most likely to affect the savannah food web?
