Can elodea photosynthesize in dark?

The Elodea in the dark lacked light for photosynthesis, so CO₂ levels should have increased and O₂ levels decreased as respiration occurred.

Can elodea perform photosynthesis without light?

Through experimentation, students conclude that light is necessary for photosynthesis. Observe chloroplasts and identify both the stem and the leaves of an Elodea plant as areas where photosynthesis occurs.

How do elodea plants photosynthesis?

How can I use Elodea to study photosynthesis? During photosynthesis, the plant absorbs carbon dioxide from the water and releases oxygen. Since oxygen is much less soluble in water than is carbon dioxide, the water quickly saturates with oxygen and bubbles form.

What happens when an elodea plant is grown in bright light?

The independent variable is the distance from the light source, the dependent variable is the rate of photosynthesis and the constant is the time the elodea is exposed to the light. If the elodea is closer to the light, then the rate of photosynthesis will be faster because plants need light to photosynthesize.

What is the relationship between water light and co2 and photosynthesis?

Light provides the energy for photosynthetic pigments to convert carbon dioxide (CO2) and water into sugars and oxygen. As light intensity increases Ð until a point Ð the amount of sugars increases and thus, more energy is available for plant growth and maintenance.

What gas did the elodea plant give off in the light?

They produce carbon dioxide during cellular respiration. In this experiment, the student will place aquatic plants under different colors of light in a solution of bromothymol blue.

What important gas do we take in when we breathe gizmo answers?

What important gas do we take in when we breathe? Oxygen 2. Why don’t we run out of the important gases that we need to stay alive? They are always in the air.

Does elodea produce carbon dioxide?

Snails will produce only carbon dioxide, while the Elodea will produce carbon dioxide and oxygen gas. Snails and Elodea will produce more carbon dioxide, causing the water to turn yellow.

Do producers give off carbon dioxide?

Producers convert water, carbon dioxide, minerals, and sunlight into the organic molecules that are the foundation of all life on Earth.

Why do producers give off carbon dioxide?

During photosynthesis, plants and other producers transfer carbon dioxide and water into complex carbohydrates, such as glucose, under the influence of sunlight. Animals are called consumers, because they use the oxygen that is produced by plants.

Do consumers give off or take in carbon dioxide?

Explanation: The consumers give off carbondioxide, which is essential for production of food by the process of photosynthesis. The carbon dioxide is utilised for the syjnthesis of simple monosaccharide i.e., glucose.

What is the best answer to why nutrient cycling is essential to life on Earth?

Nutrient cycles link living organisms with living organisms, living organisms with the non-living organisms and non-living organisms with non-living organisms. This is essential because all organisms depend on one another and is vital for the survival of living organisms.

Why the cycling of nutrients depends on gravity?

The cycling of nutrients is also the source of energy, and the resource is limited. Gravity allows the planet to hold onto its atmosphere and helps to enable the movement and cycling of chemicals through air, water, soil.

Do nutrients cycle or flow through an ecosystem?

Energy and nutrients, or chemicals, flow through an ecosystem. While energy flows through the ecosystem and cannot be recycled, nutrients cycle within an ecosystem and are reused.

How does the nutrient cycle work?

The nutrient cycle is a system where energy and matter are transferred between living organisms and non-living parts of the environment. This occurs as animals and plants consume nutrients found in the soil, and these nutrients are then released back into the environment via death and decomposition.

How do some ecosystems produce plant matter faster than others do?

Some Ecosystems Produce Plant Matter Faster Than Others Do o Net primary productivity (NPP) is the rate at which producers use photosynthesis to produce and store chemical energy minus the rate at which they use some of this stored energy through aerobic respiration.

What happens to matter in ecosystems and the biosphere?

Any nonliving matter that living things need is called a nutrient. Carbon and nitrogen are examples of nutrients. Unlike energy, matter is recycled in ecosystems. Decomposers release nutrients when they break down dead organisms.

How do energy and matter move through an ecosystem quizlet?

How does matter and energy flow through a ecosystem ? Plants use minerals and gases from the air. herbivores get there matter and energy from the plants they eat. carnivores get the energy and matter from the animals they eat.

What are the major components of biosphere?

Biosphere has three basic components. These are (A) abiotic (physical and inorganic) components; (B) biotic (organic) components and (C) energy components.
