Answer: Genetics and Pressures
Explanation:
For natural selection to occur, a population must have a wide variety of individuals with different traits. For example, natural selection would not influence fish body color if all individuals in a population were exactly the same color. Variation of scale color can help a fish species have a higher chance of survival by confusing predators as to what species they are.
Reproductive strategies represent a set of behavioral, morphological, and physiological adaptations that facilitate access to potential mates, improve the chances of mating and fertilization, and enhance infant survival. Male peacocks have bright, big tail feathers, for example, to attract females. If an organism has a high appeal, this will make them more likely to be able to meet and continue the survival of the species.
Environmental pressures, such as plant death, could influence the survival of herbivorous organisms. Say a small land creature consisted off grass, and an epidemic killed all the grass in their region. They would either die off, or they would evolve to find different types of food. The former could reduce population, while the latter could increase it.

Answer:
No, there are no organisms that will not fall into these categories
Explanation:
Living organisms interact with one another in their natural environment in order to ensure that energy needed for their metabolic activities is obtained. To do this, each organism plays different or specific roles. The roles that every organism must fall into are as follows:
- Producers are groups of organisms that have the ability to synthesize their own food using light (photosynthesis) or chemicals (chemosynthesis). Examples are green plants, algae, some bacteria etc.
- Consumers- These are organisms that lack the ability to synthesize their own food and hence depend on other organisms for their energy source. Consumers can either be herbivores (eat plants) or carnivores (eat flesh) etc. Examples are all animals etc.
- Decomposers- These are organism that have the ability to breakdown dead organisms into organic matter, thereby, adding nutrients back to the soil. Examples are fungi, bacteria, earthworm etc.
Based on this explanation above, no organism will not fall into any of these three categories. Some can even occupy two roles.
