1. Individual: any living being.
2. Population: same group of species that live in a paricular geographical area.
3. Community: a group of interdependent organisms of different species growing or living together in a specified habitat
4. Ecosystem: a community of living organisms called producers, consumers, and decomposers.
5. Biosphere: region of the surface, atmosphere, and hydropsphere of the earth occupied by living organisms.
Given that,
Density of the liquid, d = 3 g/ml
Volume, V = 20 mL
To find,
The mass of the liquid.
Solution,
The density of an object is given by its mass divided by volume such that,
d = m/V
m is mass
m = d×V
Put all the values,
m = 3 g/mL × 20 mL
= 60 grams
Hence, the mass of a liquid is 60 grams.
Explanation:
cost
- ongoing maintenance
- initial design and construction
benefit
- protection of infrastructure
- lower insurance costs
- employment opportunities
The flood mitigation projects have initial startup costs and ongoing maintenance costs over the years. However, apart from the costs, these have additional benefits like lower insurance costs due to protected infrastructure and reduced flood damage, along with employment opportunities during building and maintenance.
Further Explanation:
Flooding usually happens when lots of rainfall occurs in relatively short time periods. These are usually enough to cause rivers to overflow their banks and also occur when storms force large volumes of water from the ocean to travel inland. Typically these occur in arid ecosystems, having low average rainfall- the water accumulates in dry regions and saturates the area. This phenomena are majorly destructive and can uproot trees, destroy bridges, buildings and other infrastructure while leading to loss of life.
