If the producers were removed then there would be no beginning to the food chain and the complete ecosystem would die off. If the detrivores and decomposers were removed there would be no organic nutrients and all the dead plants would ruin the animals habitat.The ecosystem will be fill by plants and animal wastes as <span>there will be no decomposition of waste material.</span>
Answer:
The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.
Explanation:
During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.
The previous statement is true because if a substance cannot get into a cell membrane it is assisted via protein channels however if it doesn't need the protein channels then it just flows through the membrane.

<h3>⇝ <u>Epidermis</u> :</h3>
Protective tissues includes epidermis & cork. Epidermis is basically a simple permanent tissue, protective in function. It forms one-cell-thick covering over all the parts of plant.
<h3>⇝ <u>Characteristics of Epidermis</u> : </h3>
- Epidermis is formed of living cells, arranged in a single layer.
- In aerial parts, epidermis is covered with a waterproof and noncellular waxy covering called cuticle.
- Cells form a continuous layer, but in leaves epidermis has small openings called stomata.
- Each stoma is guarded by a pair of bean-shaped guard cells which govern opening & closing of stomatal aperture.
<h3>⇝ <u>Functions of Epidermis</u> :</h3>
- Epidermis protects the underlying tissues from mechanical injury, chemicals & infection.
- Cuticle of epidermis protects against water loss & desiccation. It checks the rate of transpiration & evaporation and prevents wilting.
- Stomata in the epidermis of leaves help in gaseous exchange during respiration & photosynthesis.

<h3><u>Answer;</u></h3>
The adrenal glands sit on top of the kidneys and release adrenaline, which affects heart rate.
<h3><u>Explanation;</u></h3>
- Adrenal glands are located at the top of each kidney. They produce hormones that help the body control blood sugar, burn protein and fat, react to stressors like a major illness or injury, and regulate blood pressure.
- The Adrenal glands are made up of two regions; the adrenal cortex and the adrenal medulla. <em><u>The adrenal medulla produces hormones adrenaline also epinephrine and noradrenaline also norepinephrine. </u></em>
- <em><u>Hormone adrenaline rapidly responds to stress by increasing your heart rate and rushing blood to the muscles and brain.</u></em>
