What are two types of secondary succession?
-
succession, and
succession
Answer:
Fire. Fire is one of the most common causes of secondary succession and is an important component for the renewal and vitality of many types of ecosystem.
Harvesting, Logging and Abandonment of Crop Land.
Explanation:
1- After a fire, species start to recolonize an area, beginning the secondary succession process. The first species to colonize are usually fast growing herbaceous plants, such as conifers or ferns, which require high levels of light. These species are often already present in the form of seeds within the soil, or are able to rapidly disperse from nearby areas. In time, slow growing, shade-tolerant, woody species begin to suppress the early successional species, which are in-turn replaced or shaded by large trees, eventually leading to the generation of forests and a climax community.
2- The abandonment of land previously utilized for crops is a common cause of human-induced secondary succession. Land which has been intensively cultivated is often nutrient poor, with the nutrients having been repeatedly removed through harvest or logging. Agricultural processes also often leave the soil vulnerable to high levels of erosion. The abandonment of such land allows plants and animals that were previously unable to inhabit the area to colonize. Early succession of vegetation following the abandonment of farmland is responsible for increases in soil organic content, nutrient density and soil porosity. The addition of shrubs and of root systems within the soils, which follow in later succession, acts as a natural barrier against erosion, thereby allowing for restoration of degraded habitats.
Secondary succession is a type of ecological succession in which plants and animals recolonize a habitat following a significant disturbance, such as a devastating flood, wildfire, landslide, lava flow, or human activity.
Thus, Primary succession, in which a biological community emerges where none previously existed, is distinguished from secondary succession.
Where a disturbance did not completely wipe out all life and nutrients from the environment, secondary succession occurs.
Despite the fact that fire, flooding, and other disturbances can leave a landscape in ruins, drive many animals and plants away, and bring the biological community back to an earlier stage, the habitat is still alive because the soil still contains nutrients and seeds that were sown before the disturbance and animals.
Thus, Secondary succession is a type of ecological succession in which plants and animals recolonize a habitat following a significant disturbance, such as a devastating flood, wildfire, landslide, lava flow, or human activity.

Answer:
First read the student guide to understand everything that will occur in this lab. Second read the safety guideline to ensure no one is harmed during this lab. Then gather your materials for the lab. After that section off your grass into 32 sections. Choose a quadrant and make some observations. Then choose a random sample area in your quadrant to estimate how many individual pieces of grass are present. Next, find the average height of the grass. Then, compare the data to quadrant #18. Plant your seeds. Count how many blades of grass are in your random sample area, and then calculate the estimated number of blades in your quadrant. Find the average height of the grass. Compare your data once again to quadrant #18, which is in the control group. Record the height of all the plants and calculate the average height for each type of plant. Compare this data with the data from quadrant # 18. Combine the data from all quadrants, and then compare the data from the experimental group to the control group.

Which statement est describes how organisms and populations depend on abiotic fertors in
an ecosystem?
A Algae is the main diet of tadpoles.
B Woodpeckers nest in dying trees.
с Worms dig tunnels 'n soll.
D
Gids nest in cattail plants
"Worms dig tunnels in soil", best describes how organisms and populations depend on abiotic factors in an ecosystem. Therefore, option (C) is correct.
What are abiotic factors?Abiotic factors are non-living aspects of the environment that have an effect on living things. In this scenario, worms are considered to be biotic factors; however, the abiotic factor of soil is required for the worms' tunneling activity in the soil. The behavior of worms and the impact that they have on the ecosystem can all be influenced by the moisture level, texture, and nutrient density of the soil.
Therefore, choice (C) illustrates how organisms' ability to survive and perform their roles within an ecosystem is contingent on the presence of abiotic factors.

how does independent assortem increase genetic diversy
Answer:
Genetic diversity is increased by independent assortment (genes are inherited independently of each other) and crossing over during meiosis. During meiosis, chromosomes (which are found in pairs) swap large portions of their molecules, causing genetic material to be mixed between them.
Explanation:
What proportion of each parent plant's genetic material does each offspring plant have?
Answer:
Each gamete comprises half of the organism's chromosomes, or genetic material. As a result, each sperm carries 50% of the father's genes and each egg carries 50% of the mother's genes. This distinguishes gametes from other cells in the body.

2. Suggest 2. -3 important considerations and/or measures that the crew should take to ensure the plants ability to survive and photosynthesize. Justify your ideas by explaining why they are necessary.
Can someone please help me on this?
Answer:
Provide food stuff and oxygen.
Explanation:
Making of food and supply of oxygen are the two biological benefits that photosynthetic plants provide to the crew of the ship. The plants make their own food for itself as well as for other organisms and also release oxygen that is produced in the process of photosynthesis. The crew should placed the plants in the sunlight and provides water daily in order to survive and photosynthesize. The sunlight and water are very important because sunlight opens the stomata through which carbondioxide gas enters into the leaves which combines with the water forming glucose and oxygen. Glucose is stored in the plant body whereas some oxygen is used by the plant during respiration and the extra is released in the air through stomata.

how do the kidneys and the bladder work together??
Answer:
From the kidneys, urine travels down two thin tubes called ureters to the bladder. The ureters are about 8 to 10 inches long. Muscles in the ureter walls constantly tighten and relax to force urine downward away from the kidneys. If urine is allowed to stand still, or back up, a kidney infection can develop.

Kidney: excretory and respiratory
The skin integumentary system and immune system are pairs of an organ that functions in two different organ systems.
How do the Skin integumentary system and immune system work together?The skin and other parts of the integumentary system work with other organ systems to maintain homeostasis. The skin works with the immune system to defend the body from pathogens by serving as a physical barrier to microorganisms.
