Define trophic level. |
|
Answer» Thanks The trophic level is the position an organism occupies in the food chain. The first trophic level known as the base of the ecosystem has the highest energy concentration which is transferred to the organisms at different trophic levels. Following are the different levels of an ecosystem:\tProducers: Plants and other autotrophs are known as producers. They prepare their own food using sunlight and carbon dioxide by the process of photosynthesis. This energy is transferred to the organisms that feed on the producers.\tPrimary Consumers: This is the second trophic level which includes all the herbivores. Animals such as cows, buffaloes, deer, few insects cannot prepare their food and rely on plants and natural products for nutrition.\xa0\tSecondary Consumers: A few organisms such as rats, foxes, fish belong to the third trophic level. These are secondary consumers and derive their nutrition from the primary consumers.\xa0\tTertiary Consumers: This is the fourth trophic level that includes all the carnivores and omnivores.\xa0\tApex Predators: This is the final trophic level of the ecosystem. The animals belonging to this trophic level have no predators of their own. Eagles, lions, anacondas, belong to this trophic level. |

What is electric induction |
|
Answer» Electromagnetic Induction was discovered by Michael Faraday in 1831 and James Clerk Maxwell mathematically described it as Faraday’s law of induction.Electromagnetic Induction is a current produced because of voltage production (electromotive force) due to a changing magnetic field. Electromagnetic or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday\'s law of induction. Electromagnetic Induction is the governing principle that is used to explain how electric generators (also called alternators), microphones, electric guitars, and transformers operate.The current contained in the conductor is said to alternate because its current flows back and forth, as a result of the conductor being first raised and then lowered in the magnetic field. In short, currents help to create magnetic fields.A moving or changing magnetic field does produce a current in a current loop or a voltage across the ends of a current loop. This is called electromagnetic induction and the current or voltage is called an induced current or an induced voltage. |

What is the job of liver |
|
Answer» Liver is the largest gland in human beings.Its main functions are as follows:\tIt secretes bile juice which makes the medium of the food alkaline and also emulsifies fat.\tIt stores the excess of glucose in the form of glycogen.\tOld worn-out RBCs are broken down in liver cells. Their haemoglobin is changed into bile pigments.\tThe ammonia is produced as a result of metabolism of amino acids.

What is nutrition in amoeba |
|
Answer» The mode of nutrition in Amoeba is holozoic and various steps involved in the process of nutrition are:\t Ingestion: Amoeba ingests food with the help of its finger-like extensions, called pseudopodia, when a food particle approaches Amoeba it forms pseudopodia around it and forms a food vacuole inside the Amoeba\t Digestion: Various enzymes from the cytoplasm enter into the food vacuole and break them down into simple soluble molecules\t Absorption: The simple soluble food is absorbed by cytoplasm of Amoeba from food vacuoles through the process of diffusion\t Assimilation: Amoeba cell obtains energy from the absorbed food through respiration and this energy is utilized by Amoeba for its growth and repair of the body\t Egestion: When a considerable amount of undigested food gets collected inside Amoeba, its cell membrane ruptures and throws out the undigested food.

Write 2 rules Of the new cartesian Sign convention for spherical mirrors |
| Answer» According to the New Cartesian Sign Convention, the pole (P) of the mirror is taken as the origin. The principal axis of the mirror is taken as the x-axis (X’X) of the coordinate system. The conventions are as follows:(i) The object is always placed to the left of the mirror. This implies that the light from the object falls on the mirror from the left-hand side.(ii) All distances parallel to the principal axis are measured from the pole of the mirror.(iii) All the distances measured to the right of the origin (along + x-axis) are taken as positive while those measured to the left of the origin (along – x-axis) are taken as negative.(iv) Distances measured perpendicular to and above the principal axis (along + y-axis) are taken as positive.(v) Distances measured perpendicular to and below the principal axis (along –y-axis) are taken as negative. | |
