Identify the following as abiotic or biotic. a paramecium swimming in a lake

Biotic

We are being tested on whether we can differentiate between abiotic and biotic factors in an ecosystem.

Then, what is the difference between abiotic and bioitic factors?

What are examples of Biotic and abiotic factors.

How do we arrive at the answer to our question?

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
