Biological transmission involves reproduction of pathogens in an arthropod vector prior to transmission. In terms of epidemiology, we can term a vector as an organism that is from infected to the uninfected. An infected organism which develops biological vector passes it to its host. For example a mosquito.

 A mosquito being a mechanical vector carries an infected organism to its host either through the legs or through the other body parts

Amoeba paramecium and spirogyra are diverse. why then are they all classified as protists
allochka39001 [22]
Even though amoeba, paramecium, and spirogyra are quite different, they are all often classified in the same group, Protista because this group holds various types of eukaryotic organisms that are heterotrophic and unicellular.
This type of classification is not based on evolutionary and genetic similarities, but only on the properties of being unicellular, so there are many vastly different organisms in this group.

All materials within ecosystems can be recycled.
netineya [11]

Answer:

All the things expect enegry are recycled.

Explanation:

  • When the decomposer decomposes the organic substances than they are taken by plants in the form of nutrition and minerals. Likewise, the food prepared by the plants are taken by animals and the nutrition is recycled.
  • The oxygen and carbon dioxide cycle is also recycled. When the animals releases carbon then the plants take it and gives out the oxygen. In this way oxygen and carbon dioxide cycle is also maintained in nature.

But incase of enegry it cannot be recycled but frequently transfered from one form to another form.
