Try to make each of the food chains you select as different as possible. On your two selected food chains, identify the producer, primary consumer, secondary consumer and tertiary consumer. Food chain 1:
Producer: Acacia Senegal Tree
Primary consumer: African Giraffe
Secondary consumer: Leopard
Tertiary consumer: Lion

Food Chain 2:
Producer: Jackal Berry Tree
Primary consumer: Antelope (Impala)
Secondary consumer: Cheetah
Tertiary consumer: Crocodile
List two top carnivores in your food web. African Wild Dog Leopard Explain what would happen if all the primary consumers became extinct. Avoid exaggeration. If all the primary consumers of the food web I created were to be removed, the food web as a whole would breakdown, and this would cause extinction of species, migration, and possibly even evolution. This would happen because if there weren’t primary consumers, producers of the food web would run out of space and also resources. All of the food chains trophic levels would be impacted. Describe what would happen if all the decomposers became extinct. Avoid exaggeration. If all of the decomposers of the food web I created were to become extinct, the ecosystem would then lack of organic nutrients, and all the dead plants would ruin the animal’s habitat. If this happens this ecosystem would be the filled with plant and animal waste and it will result as a total disaster. If this were to happen there wouldn’t be life because plants wouldn’t be getting nutrients. Explain what would happen if a non-native species severely depleted the population of producers in your food web. If a non-native species were to deplete the population of producers in the food web I created then the animal species following the population of producers wouldn’t be getting the amount of energy they need because they wouldn’t have enough food and would have to look for another food source causing a shift in the food web. Explain why food webs with many species are more resilient than those with few species. I believe that food webs with many species is more resilient than those with few species because the species have more options of food, which means that if one species of the food web dies it doesn’t have that much of an impact because it can be replaced, however if the food web has few species the loss of one would have a greater impact to the whole food web.
