which organelles in the animal cell is the site cellular respiration where food energy is converted into cellular energy in the form of atp

The mitochondria (specifically the inner membrane/inner membrane space) is the place where ATP is generated from glucose and oxygen via oxidative phosphorylation. The initial stages where glucose is converted to pyruvate occurs in the cytoplasm.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
