The interrelationship between the Elodea plant and paramecia in a pond system is mutualism.
The pond system is a type of an artificial aquatic system that contains organisms (plants and animals) that are regularly maintain.
The Interrelationship between organisms which can occur in an ecosystem include:
- competition,
- predation,
- commensalism,
- mutualism and
- parasitism.
Mutualism occurs when two organisms of different species benefits from each other.
The Elodea plant purifies the water through photosynthesis and provides habitat for the paramecia
The paramecia in turn generates carbondioxide through its body surface which is a key element used for photosynthesis by the Elodea plant.

The correct answer is the Phenotype.
The phenotypic ratio of 9:3:3:1 is the ratio associated with a dihybrid cross. It is a classical Mendelian example of independent assortment. It is a result of crossing two organisms that are heterozygous for two traits.
Answer:
One distinguishing characteristicof all three clades i.e Deuterostomia, Lophototrochozoa, or Ecydysozoa are balstopore development, internal body cavity and exoskeleton respectively
Explanation:
Apart from molecular difference, there exist structural differences between the three clades, which are as follows –
Deuterostomia – The development of embryo is different from the protostomes as the first opening in this clade is anus and the blastopores develops into the anus.
Lophototrochozoa – They do not have ant distinguished internal body cavity. Organs with in coelom can move freely. For example - flatworm
Ecydysozoa – have the ability to shed their tough and flexible exoskeleton i.e cuticle , several times throughout their life span
It’s is c the anogiosperms
