What relationship might exist between fish kill events and rainfall?

Large rain events

Explanation:

They can also rapidly circulate the water in a lake or pond, causing changes in the position of oxygen rich water in a short period of time. This quick 'turnover' of the water can quickly decrease the amount of oxygen available to fish, essentially causing them to suffocate.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
