Oxygen is used by both autotrophs and heterotrophs to release energy from glucose (as we know, the bonds between organic compounds can be used to release energy) in a process known as cellular respiration. Carbon dioxide, however, is predominantly used in autotrophs to perform photosynthesis because they cannot get their food any other way. The type of organism that is both an oxygen producer and carbon dioxide consumer is an autotroph. This is because they release oxygen during photosynthesis and require carbon dioxide to perform photosynthesis.

Answer:
The size of a seed in a specific plant is transmitted as a polygenic trait. When crossing between two true-breeding varieties takes place, the heterozygous individuals are obtained in the F1 generation. When these F1 offspring are backcrossed with one of the parents, there will be an increase in the variance. This is due to the fact that the backcross progeny are not uniformly heterozygous at the seed size loci.
When one of the links (species) in a food chain is no longer present (for example a species goes extinct or a feral animal takes over), the food chain breaks. Sometimes, this can cause other animals in the food chain to disappear as well and the whole ecosystem can become imbalanced or even collapse.
Zoologists study the animal kingdoms. So, in the rainforest, they would study the animals that live in the trees.
