Answer:
In grassland ecosystem, first trophic level is the producer. Producers are the organisms which makes their own food, here the producer are grasses. The second trohic level contain herbivores which feed on these grasses. These herbivores are eaten by secondary consumers which belongs to third trophic level and secondary consumers are then eaten by tertiary consumer.
The population of producers are very high so it is placed at the base while tertiary consumer are placed on the top due to low population.
Most dietary <u>fats </u>are too large to be assimilated and absorbed into the capillaries but they are otherwise absorbed into the lacteals.
<h3>What are dietary fats?</h3>
Dietary fat is necessary for good health. It offers you strength and aids in the absorption of vitamins by your body. Dietary fat has about twice as much energy per gram as carbs and protein.
In the villi ( an organ in the small intestine) is located the lacteal which is a lymphatic capillary that absorbs and assimilates dietary fats.
Most nutrients are also absorbed through the blood capillaries, but as for dietary fats and fat-soluble vitamins, they are absorbed by the lacteals.
