Question

Сравнить питание растений и животных, помогите

Answer 1

Ответ:

Растения- автотрофы, т. е. они сами вырабатывают органические вещества из неорганических(процесс фотосинтеза)

животные- гетеротрофы, т е они питаются готовыми органическими веществами(животные могут быть травоядными, плотоядными, всеядными)

Answer 2

удачи можно 5 и лучший ответ

Answer 3

Comparison of Plant and Animal Nutrition

When comparing the nutrition of plants and animals, there are several key differences to consider. Let's explore these differences in more detail:

1. Energy Source: Plants are autotrophs, meaning they can produce their own food through photosynthesis. They use sunlight, water, and carbon dioxide to synthesize glucose and other organic compounds. Animals, on the other hand, are heterotrophs and rely on consuming other organisms for their energy and nutrients.

2. Nutrient Requirements: Plants require a variety of nutrients to support their growth and development. These include macronutrients such as nitrogen, phosphorus, and potassium, as well as micronutrients like iron, zinc, and magnesium. They obtain these nutrients from the soil and through the process of absorption. Animals, on the other hand, require a balanced diet that includes proteins, carbohydrates, fats, vitamins, and minerals. They obtain these nutrients by consuming plants or other animals.

3. Digestive Systems: Plants have a cell wall made of cellulose, which is difficult to break down. They have specialized structures, such as chloroplasts and vacuoles, that aid in the digestion and storage of nutrients. Animals have a more complex digestive system, including organs like the stomach, intestines, and liver. They have enzymes that break down food into smaller molecules for absorption and use by the body.

4. Feeding Strategies: Plants have various strategies for obtaining nutrients. Some have roots that absorb nutrients from the soil, while others have specialized structures like carnivorous plants that capture and digest insects for additional nutrients. Animals have different feeding strategies depending on their diet. Herbivores consume plant material, carnivores eat other animals, and omnivores have a mixed diet of both plant and animal matter.

5. Growth and Reproduction: Plants have the ability to grow throughout their lifespan, with continuous cell division and elongation. They can reproduce through both sexual and asexual means, such as pollination and vegetative propagation. Animals have a limited growth period and reach a certain size before maturity. They reproduce sexually, with the fusion of gametes from male and female individuals.

In summary, plants and animals have different nutritional requirements and strategies for obtaining nutrients. Plants are autotrophs that produce their own food through photosynthesis, while animals are heterotrophs that consume other organisms. Plants have specialized structures for digestion and absorption, while animals have a more complex digestive system. Additionally, plants have continuous growth and can reproduce through both sexual and asexual means, while animals have limited growth and reproduce sexually.
