Animals are categorised on the basis of their nitrogenous waste products. They are:
1. Ammonotelic animals are animals which excrete nitrogenous wastes as ammonia.
2. Ureotelic animals are animals which excrete nitrogenous wastes as urea.
3. Uricotelic animals are animals which excrete nitrogenous wastes as uric acid.

Hence, Tadpole is ammonotelic because it lives in water and has a large volume of water that is needed for the elimination of ammonia. It can eliminate ammonia was rapidly as it is formed, into the surrounding water.

Adult frog is ureotelic because urea is far less toxic than ammonia and can be concentrated in the urine and excreted at slower rate.

¶¶ Correct Option (b) ammonia in tadpole and urea in adult frog.

Explanation: Ammonia is the main nitrogenous waste. It is soluble in water and highly toxic. A large amount of water is required for its excretion. Tadpole is aquatic and lives in plenty of water so, nitrogenous wastes in tadpole are eliminated as ammonia. Frog being amphibious, excretes its nitrogenous wastes as urea.

Option [b] becoz--->

As v know that Tadpole is the younger form of frog, which lives in water. Ammonia is released in organisms living in water due to its highly toxic nature.Thus, tadpole releases ammonia as nitrogenous waste.-----[WHERE AS]----- frog is an amphibian which can survive both on land as well as water.This is the reason for release of less toxic waste from frog in form of urea.

Similar Class 10 Doubts

Read the extract given below and answer the questions that follows:There are many activities that are undertaken by directly using natural resources. When we produce a good by exploiting natural resources, it is an activity of the primary sector. Since most of the natural products we get are from agriculture, dairy, fishing, forestry, this sector is also called agriculture and related sector. The secondary sector covers activities in which natural products are changed into other forms through ways of manufacturing that we associate with industrial activity. It is the next step after primary. The product is not produced by nature but has to be made and therefore some process of manufacturing is essential. After primary and secondary, there is a third category of activities that falls under tertiary sector and is different from the above two. These are activities that help in the development of the primary and secondary sectors. These activities, by themselves, do not produce a good but they are an aid or a support for the production process. The various production activities in the primary, secondary and tertiary sectors produce a very large number of goods and services. Also, the three sectors have a large number of people working in them to produce these goods and services. The value of final goods and services produced in each sector during a particular year provides the total production of the sector for that year. And the sum of production in the three sectors gives what is called the Gross Domestic Product (GDP) of a country. It is the value of all final goods and services produced within a country during a particular year. GDP shows how big the economy is.Q. Which of the following statement is not true?
