How does a decrease/decline in a top predator impact biodiversity in an ecosystem?

Biology
1 answer:
vivado [14]2 years ago
5 0

Answer:

Results in biodiversity loss due to the proliferated growth of prey that feeds on smaller species

Please find the explanation below

Explanation:

In an ecosystem, organisms feed on one another to obtain energy. In this process organisms called CONSUMERS kill and feed on one another in a process called PREDATION. Top predators are those consumers that are found at the peak of the food chain.

A reduction in the number of top predators/tertiary consumers in an ecosystem means that the secondary consumers they feed on (prey) will grow and reproduce beyond control, hence, causing them to pose serious threat to the population of smaller species below them in the food chain.

Therefore, a decrease/decline in a top predator will impact biodiversity by causing it's loss, as organisms in lower level of the food chain will drastically diminish.

You are less likely to see a total solar eclipse than a total lunar eclipse because
sergejj [24]
Lunar eclipses are more wildly visible because Earth casts a much larger shadow on the moon during a lunar eclipse than the moon casts on Earth during a solar eclipse. As a result, you are more likely to see a lunar eclipse than a solar!. ;)

Describe some improvements in the abiotic factors that support plant growth
aleksklad [387]
Abiotic variables found in terrestrial ecosystems can include things like rain, wind, temperature, altitude, soil, pollution, nutrients, pH, types of soil, and sunlight. The boundaries of an individual abiotic factor can be just as unclear as the boundaries of an ecosystem.These are often referred to as abiotic factors. Abiotic factors are non-living elements found within an ecosystem. There are six abiotic factors that affect plant growth: air, water, space, temperature, light and soil (nutrients).The two most important abiotic factors affecting plant primary productivity in an ecosystem are temperature and moisture.


LEARNING OBJECTIVE[ edit ]

Identify the abiotic factors that affect plant growth

KEY POINTS[ edit ]

Primary production, on which almost all of life on earth is dependent, occurs through either photosynthesis or chemosynthesis.
Annual biomass production, used to estimate net primary productivity by plants in an area, is directly influenced by an environment's abiotic factors, which include temperature and moisture.
Warm and wet climates have the greatest amount of plant biomass because they offer conditions in which photosynthesis, plant growth, and the resulting net primary productivity are highest.
TERMS[ edit ]

biomass
the total mass of all living things within a specific area, habitat, etc.

eco-region
a region, smaller than an ecozone, that contains a distinct biodiversity of flora and fauna

chemosynthesis
the production of carbohydrates and other compounds using the oxidation of chemical nutrients as a source of energy rather than sunlight; it is limited to certain bacteria and fungi
