The correct answer is option a. only 10 percent of the energy at each trophic level is passed on to the next level.

The producers obtain their energy from the sunlight and convert it into usable form of energy for consumers. The primary consumers eat the plants, and obtain energy from the plants. On each trophic level, only 10 % energy is transferred to the succeeding one.

As only 10% of the energy is transferred to the next trophic level, the primary producers need to eat more plants in order to meet their energy requirement. This insufficiency of the energy transfer from one trophic level to another causes the decrease in the biomass on next level.

________ attach skeletal muscles to bones, and ________ connect one bone to another

Kay [80]

Answer: B. Tendons; ligaments

Explanation: Tendons are white, inelastic and tough connective tissue that attach skeletal muscle to bone. Tendons attach muscles to structures such as the eyeball. Fibres in tendons are arranged as compact parallel bundles.

A ligament is a yellow, elastic and strong fibrous connective tissue which attaches bone to bone. Ligaments usually hold bones together and keep them stable. Fibres of the ligament are compactly packed and but they are not arranged in parallel bundles as that of tendons.

Two species of birds feed on mistletoe berries. The birds are active at different times of the day and do not come into contact

I am Lyosha [343]

Answer:

The correct answer is B. exploitation

Explanation:

Exploitation competition occurs when the interaction of two species is indirect when they complete for the same resource like food, place, etc. The use of resources by one individual species reduces the amount of resources for the other species leading to competition.

So over time the more fit species will out complete the less fit species. So here two species of bird feed on the same food but at different times and so they reduce resources for each other which is an example of exploitation competition.

Answer:

As one example, think about a building's electrical system. Suppose a mouse chewed through an electrical wire to a furnace. Without electricity, the heating system would not work. If this happened in very cold weather, the plumbing system could be affected. Water pipes might freeze and burst. If a lot of water leaked into the building's walls, its support system would be damaged. Like a building's systems, your body's systems have

Explanation:

You know that your body is made of cells. When groups of cells do the same kind of work, they are called tissues. The word tissue comes from a Latin word meaning to "weave." Cells that make up tissues are sometimes "woven" together.

You have four main types of tissues: epithelial, nervous, muscle, and connective tissue. Epithelial tissue covers the outside of the body. It also lines organs and cavities. Nervous tissue sends electrical signals. Muscle tissue helps you move. Connective tissue joins bones and cushions organs.

When groups of tissues work together, they are called organs. Some

examples of organs are the heart, lungs, skin, and stomach. When organs work together, they are called systems. For example, your heart, lungs, blood, and blood vessels work together. They make up the circulatory system.

There are eleven systems in the human body: muscular system, respiratory system, digestive system, integumentary system (skin), skeletal system, circulatory (or cardiovascular) system, excretory (or urinary) system, reproductive system, nervous system, lymphatic system, and endocrine system. Each system has a special job.

All of your body systems have to work together to keep you healthy. Your bones and muscles work together to support and move your body. Your respiratory system takes in oxygen from the air. It also gets rid of carbon dioxide.

Think of your body as a building. A building has a plumbing system, a heating system, a cooling system, an electrical system, and a support system. If any system in a building breaks down, other systems can be affected.
