They eat berries and mushrooms, as well as animals such as salmon and deer.Primary consumers areherbivores. What are some invasive species in the tundra biome? You do not have to consume any other organisms to get your energy, making you an autotroph. Only a thin layer of humus (the organic component of the soil formed by incomplete decomposition of plant or animal waste) supplies nutrients to the plants. When we're talking about their role in food chains, we can call autotrophs. In the savanna, the lowest trophic level often includes shrubs and sparse trees, including palms, pines and acacias. Some of these include birds, insects, and small mammals. Biomass is the energy in living organisms. Scientists believed they had discovered a miracle drug. These plants attract and trap preyusually insectsand then break them down with digestive enzymes. In this scenario, you, as the grass, are the producer, because you make your own energy through photosynthesis.
