Yes ! Indeed plants can survive without animals thats why they are called autotrophs.

Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.

The process by which green plants make their own food (like glucose) from carbon dioxide and water by using sunlight energy (in the presence of chlorophyll) is called photosynthesis. Oxygen gas is produced during photosynthesis which is utilised by all the living organisms for their survival.

Answer. Plants are called autotrophs because they can use energy from light to synthesize, or make, their own food source. Rather, plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive.

Plants don’t eat food. They use the energy from the sun, or other light and use it to make their food. The ingredients for this process are water, air, and light. Plants don’t use all the parts of the air, they only use the carbon dioxide (CO2) to make their food.

Now in simple, cellular respiration uses glucose and oxygen to create ATP energy, and exhausts CO2 and water. So since cellular respiration exhausts CO2, other plants inhale that CO2 and make it possible for plants to live completely by themselves. Without humans, plants would still live the exact same.

Without plants, animals would have no oxygen to breathe and would die. People also depend on plants for food. All animals eat either plants or plant-eating animals.

Humans and plants have a complex relationship extending far back into our joint evolutionary history. This legacy can be seen today as plants provide nutrition, fiber, pharmaceuticals, and energy for people and animals across the globe.

All plants can survive for short periods without light. The plants have no chlorophyll and get all their nutrients by parasitically attaching to the roots of nearby plants instead. Although broomrape doesn’t harness sunlight itself, it is still indirectly reliant on the Sun to provide energy to its host plant.

Chinese Evergreen (Aglaonema) Chinese Evergreen plants are one of the best plants to grow indoors that don’t require constant, direct sunlight. If you are someone who’s new to growing houseplants, this is the plant you should start with.

Air plants can grow literally anywhere—no soil needed. We love them propped up on a shelf, or hanging mid-air. To water, dunk them every 10 days and let them dry out after in a sunny spot. Begonias are known for their big, gorgeous leaves making a bold contrast in any room.

Annual Flowers That Do Well in Direct Sun

• petunia.
• ageratum.
• salvia.
• moss rose.
• sunflower.
• zinnia.
• marigold.
• geranium.

Tender herbs like basil (along with parsley, chives, and cilantro) thrive in direct sun. Plant basil in a well-draining potting soil in the spring, place it in a bright, south-facing window, and snip off a sprig any time you need one for a recipe.

Most plants requiring either part sun or part shade do well in filtered light for most of the day, or direct sun during the morning or afternoon. Keep in mind that several hours of afternoon sun are more intense and create more heat than morning sun. These plants may bloom poorly if given too little sun.

Light through a window is not direct sunlight as some of the light is diffused and reflected as it passes through the window, reducing its intensity. Light through a window is the most direct form of light available indoors, but is usually at least 50% less intense than direct sunlight outdoors.

Indirect light is sunlight that either passes through a medium—a window shade or the leaves of a tree—or reflects off another surface before reaching a plant. Indirect sunlight ranges from the bright indirect light of east-facing windows to the fainter, indirect light of north-facing windows.

It depends. If the sun’s rays directly hit the plant – such as through a south-facing window – this is considered direct sunlight. If the sun is bright but the rays don’t directly hit the plant, this is considered indirect light. Let’s take a deeper look at how light works when it’s filtered through windows.

Yes, your indoor plants can photosynthesize even if their light sources passes through a glass windowpane. In fact, your plants aren’t particularly discerning about what light source they use, provided the light is sufficient for photosynthesis.

All plants require light for photosynthesis, the process within a plant that converts light, oxygen and water into carbohydrates (energy). Plants require this energy in order to grow, bloom and produce seed. Without adequate light, carbohydrates cannot be manufactured, the energy reserves are depleted and plants die.

Without sunlight, the plants are unable to convert nutrients and carbon-dioxide to energy through the photosynthesis process. On cloudy days, they produce much less of the energy they need to grow and bloom. Additionally, the plants’ circulatory system slows down in cool weather.

Suitable foods to grow on a windowsill over winter include:

• Lettuce.
• Radish.
• Carrot.
• Cherry tomato.
• Hot pepper.
• Bell pepper.
• Onion.
• Spinach.

Loose Leaf Lettuce After green onions growing lettuce is one of the easiest things in the windowsill gardening! It doesn’t require a sunny window, a few hours of sunlight is enough, if not, you can also use artificial light.
