Shifts in customer tastes and emergence of substitute products are examples of threats that can affect a company's products.
Step-by-step explanation:
Shifts in customer tastes away from a company's products and the emergence of substitute products are examples of threats in the business environment.
When customer tastes change and they start preferring different products, it can lead to a decline in demand for a company's products, which can be a threat to its sales and profitability.
Similarly, when substitute products enter the market and offer similar benefits at a lower price or better quality, it can pose a threat to a company's market share and competitiveness.
