They have both. The actual tail of a snake is a relatively short bit at the end, behind the anus, similarly to any other vertebrate animals. Most of the snake's body is the torso, and the neck is also short tho
Well, the question is confusing, since White is the recessive (ususally) and red being Dominant. It would be like
RR, for all red, and
WW, for all white, or perhaps rr
Answer:Red Flower RR, White flower rr/WW
The answer is A, they are connected to all levels.
Decomposers in a food web, such as bacteria or fungi, mainly get their nutrient by decomposing dead organic matter to release carbon dioxide (when they respire)to the air for producers (which are mainly plants).
The following basic food chain (which forms food web when many of these are connected) may help you understand better:
Producer→primary consumer→secondary consumer→tertiary consumer
Since all levels in a food web is formed from organic matter (including plants and animals), decomposers feed on them to get their nutrient, so they're actually connect to all levels.
B is not correct because secondary consumers are the carnivores, which are animals that consume other animals for food and nutrient.
C is not correct because primary consumers are herbivores, which are animals that consume plants (or producers) for food.
D is not correct because autotrophs are organisms that make their own food by themselves, which are usually by photosynthesis (the process to make glucose from light energy). They're usually green plants, and the "producers" from a food web.
