Answer:
Autotrophs, producers and Plants
Explanation:
Trees occupy a special position in the food web of most of all organisms. They can belong to several specie of plants and can vary in physical traits like height, fruit kind, fruiting non fruiting aspect etc. But three things that can describe trees are:
1: Autotrophs: This is because trees can prepare their own food through the process of photosynthesis and several other organisms depend upon them for food.
2: Producers: Being able to synthesize their own food, trees are known as producers because they not only prepare their own food but also food for many other organisms like humans.
3: Plants: Because trees are just a sub category or kind of plants, the terms plants can be used to describe several characteristics of trees.

Answer:
In normal conditions, introns serve following functions in the body of an organism:
1) They contain genes of miRNA which are known as Mirtrons, reverse transcriptase, endonucleases, transposase etc.
2) It is because of presence of introns that alternative splicing of mRNA is possible. The sex determination in drosophila is based on alternative splicing.
Apart from this, alternative splicing can be useful and beneficial in an unforeseen situation such as an environmental problem which is faced by the organism for the first time.
Explanation:
Alternative splicing is an important mechanism because with the help of alternative splicing different type of proteins can be synthesized from the same pre mRNA transcript. In case suddenly the surrounding environment of an organism is changed and the environmental conditions have become extremely harsh due to which organism's life is at stake, in such situation organism may make a different type of protein through alternative splicing which can help the organism in survival.
Default splicing in Drosophila leads to the development of male off-spring while female off-spring is produced as a result of alternative splicing.
Enzymes are used to break down glucose.
Organisms that use the same resources because there may not be enough for all, so it then becomes a competition of who gets it and who doesn't.
