Plants that get nutrients from rocks will can cause chemical weathering. Generally there are two types of weathering processes: physical and chemical weathering and they result in the breakdown of rocks, minerals, etc. Plants contribute to both physical and chemical weathering. Plants that grow in fissures and cracks in the rocks, as they grow their roots extend. Over time, the rocks will be broken into smaller fragments. Many such plants also give off chemicals, most commonly humic acid. These acids help in the breakdown of iron and aluminum compounds in the subsurface. Plants also support microbial life forms that help in weathering of soil and minerals. All these process contribute to the weathering of rocks and minerals.
I hope i helped. Also sorry if there were any typos.

Answer:
It's a unit of measurement that is used to find out the country's economic output per person
Explanation:
GDP per capita is calculated by dividing the total amount of the Gross Domestic Product with the total amount of population that they have. It's a more reliable way to measure a country's wealth rather than using a GDP alone.
Higher GDP doesn't always mean that a certain country is more efficient in managing their economy compared to other country.
Countries with higher population tend to have higher GDP, but it doesn't mean that each person in that country has efficiently contributed to the country's economy.
For example, Singapore is a richer country than India even though it has a way smaller GDP. India produced a GDP of 2.719 trillion USD in 2018, while Singapore produced around GDP of 364.2 billion USD in 2018.
But, India earned that GDP by pooling out the strength from 1.353 billion population. Singapore on the other hand get that GDP from only having 5.639 million population GDP.per capita in Singapore is around 64,581.94 US , While India's GDP per capita is only around 2,009.98 USD
