Organisms that ingest whole material typically have specialized digestive systems that break down the food internally through processes like mechanical digestion and enzymatic degradation, allowing nutrients to be absorbed and utilized.

Parasitic nutritive strategy involves deriving nutrition from other organisms without killing them. Examples include parasites such as the cuscuta (amar-bel), ticks, lice, leeches, and tapeworms, which feed off the host organism’s resources without necessarily causing immediate death.

Organisms that ingest whole material typically have specialized digestive systems that break down the food internally through processes like mechanical digestion and enzymatic degradation, allowing nutrients to be absorbed and utilized.

Fungi like bread molds, yeast, and mushrooms are examples of organisms that break down food material externally through enzymatic action before absorbing nutrients.

Cows, as herbivores, have specialized digestive systems capable of efficiently breaking down plant material, while lions, as carnivores, have adaptations for hunting and consuming animal prey, such as sharp teeth and powerful jaws.

The type and availability of food material in an organism’s environment play a significant role in determining its form of nutrition. Factors such as whether the food source is stationary or mobile can influence how the organism accesses and utilizes ...

Sunlight provides the energy needed to drive the photosynthetic reactions that convert carbon dioxide and water into glucose and oxygen. Without sunlight, plants cannot carry out photosynthesis efficiently, leading to a decrease in their ability to produce energy-rich carbohydrates essential ...

The rate of photosynthesis can be measured indirectly by monitoring oxygen production using a dissolved oxygen sensor or by measuring the accumulation of glucose through chemical assays.

If sunlight is essential for photosynthesis, the plants exposed to sunlight should exhibit a noticeable increase in oxygen production or glucose accumulation compared to those kept in darkness.

Place potted plants of the same species in two groups, ensuring they receive identical amounts of water and nutrients. One group should be placed in a well-lit area where they can receive sunlight, while the other group should be placed ...
