Select all statements which describe the role of calcium in the soil/plant environment.

Answers

Answer 1

Answer: the statements are not given, so I will state the role of calcium in plants.

Calcium pectate, is responsible for holding together the cell walls of plants, it is also used in activating certain enzymes and to send signals that coordinate certain cellular activities in plants. Calcium helps to maintain chemical balance in the soil, it reduces soil salinity, and improves water penetration within soil.

When there is calcium deficiency, it leads to localized tissue necrosis causing stunted plant growth, dead leaf margins or curling on the leaves, and eventual death of terminal buds and root tips of the soil/plant.

Excess levels calcium in the soil can reduce a plant's uptake of other important nutrients such as phosphorus, magnesium, boron, potassium, copper, zinc or iron, leading to deficiencies of these nutrients.

Answer:

Decomposer

Explanation: I just did it

An organism that breaks down dead organisms and decomposes is called a decomposer, and the decomposer takes part in the decomposition process by breaking down the dead and mixing with soil.

What is the decomposer's importance?

Decomposers are of great importance as they can maintain the ecosystem by breaking down dead organic matter and recycling nutrients back into it, later, these nutrients are passed from the environment to plants, then to animals, and then back to the environment. Decomposers include bacteria and fungi that consume dead plant and animal material, breaking down complex molecules into simpler compounds that can be used by plants to grow.

Hence, an organism that breaks down dead organisms and decomposes is called a decomposer, and the decomposer takes part in the decomposition process by breaking down the dead and mixing with soil.

True or false? To make up for the loss of energy when solar energy is used by primary producers and then transferred up the food chain, a continuous supply of solar energy to the ecosystem is required.

Answers

Answer: Energy can not be lost, rather it can be converted into other forms of energy , so false.

Explanation:

To make up for the loss of energy when solar energy is used by primary producers and then transferred up the food chain, a continuous supply of solar energy to the ecosystem is not required. Thus, the given statement is false.

What is energy cycle in an ecosystem?

The energy flow in the ecosystem is important to maintain an ecological balance in the ecosystem. The producers in a food chain synthesize food by the process of photosynthesis. A part of this energy is stored within the plant species.

The energy cycle in an ecosystem is based on the flow of energy through the ecosystem. The energy from sunlight is converted by the plants them into the growing new plant materials including the flowers, fruits, branches, trunks, and roots of the plants. Since, the plants can grow by converting solar energy directly into their tissues.

Which characteristic makes fungi similar to plants?

Answers

Answer:

They are both non-mobile and eukaryotic.

Explanation:

Plants and fungi both remain stationary. They do not move around for their food. Another similarity is that they both are made up of eukaryotic cells, meaning they contain a nucleus.

Answer:

While both are eukaryotic (both have nucleus) and don't move, plants are autotrophic, making their own energy - and have cell walls made of cellulose, but fungi are heterotrophic, taking in food for energy (so they eat dead and decaying food), and have cell walls.

Explanation:

The minimum amount of muscles needed to move a joint is 2. Thus, the correct option is C.

What are Muscles?

Muscles may be defined as the bundles of fibrous tissue in animals including humans which consist of long cells that contract when stimulated and induce movements.

Muscles play numerous roles such as maintaining the overall posture of the body, moving the skeleton, storing nutrients, providing stability, assisting respiration and digestion, etc.

A joint is migrated with the cooperation of two muscles in such a way that one provokes the contraction while the other induces relaxation at the same time. This simultaneous activity of both two muscles is responsible for the proper migration of joints.

Therefore, the minimum amount of muscles needed to move a joint is 2. Thus, the correct option is C.
