Draw different trophic levels in an ecosystem with a line diagram.
Trophic levels show energy flow, starting with producers and moving to primary, secondary, and tertiary consumers.
Trophic levels represent the feeding position of organisms in an ecosystem. The main trophic levels are:
(b) Order of the differential equation: $ 5x^3 \frac{d^3y}{dx^3} - 3\left(\frac{dy}{dx}\right)^2 + \left(\frac{d^2y}{dx^2}\right)^4 + y = 0 $
