False. Consumers do not break down dead organisms and animal waste; that role is primarily performed by decomposers, such as bacteria and fungi, which break down organic matter and recycle nutrients back into the ecosystem. Consumers, including animals and humans, obtain energy by eating living organisms or organic material.
No
False. Organisms can play multiple roles in an ecosystem, such as being producers, consumers, or decomposers, depending on their life stage and environmental conditions. For example, some species may act as predators at one stage of their life and as prey at another. This complexity contributes to the dynamic interactions and balance within ecosystems.
True. Fungi play a crucial role in nutrient cycling by breaking down organic matter and releasing nutrients back into the ecosystem. This process helps to break down dead plant and animal material, releasing nutrients that can be used by other organisms.
false
False. Not all members of the domain Bacteria are parasites. Bacteria can also include beneficial or harmless organisms that do not parasitize other organisms.
(FAlse) Kingdom Protistae (protozoans) include both animal-like organisms (heterotrophs), as well as plant- like organisms (autotrophs).
False. Not all animal organisms have a backbone; those that do are classified as vertebrates, while those without a backbone are called invertebrates. Invertebrates make up the majority of animal species, including groups like insects, mollusks, and cnidarians. Therefore, having a backbone is not a requirement for classification as an animal.
Yes, that statement is true. All scavengers are indeed consumers because they feed on organic matter, but not all consumers are scavengers. Consumers include various organisms that obtain energy by eating other organisms, such as herbivores and predators, while scavengers specifically feed on dead or decaying matter. Thus, scavengers represent a subset of consumers within the broader ecological category.

False . There are far more consumers than producers.

No, 2nd consumers are carnivores
False. While most organisms require oxygen for survival, there are some anaerobic organisms that can live in environments without oxygen. These organisms have adapted to use other molecules for energy production.
